Partial functor
by David Leduc 16 Mar '15

16 Mar '15

Hi, A partial functor from C to D is given by a subcategory S of C and a functor from S to D. What is the appropriate notion of natural transformation between partial functors that would allow to turn small categories, partial functors and those "natural transformations" into a bicategory? The difficulty is that two partial functors from C to D might not have the same definition domain. [For admin and other information see: http://www.mta.ca/~cat-dist/ ]

UTP-2014 Unifying Theories of Programming - call for papers
by David Naumann 10 Jan '14

10 Jan '14

********************************************************************** 5th International Symposium on Unifying Theories of Programming co-located with FM2014 May 12 - 13, 2014 Singapore http://www.comp.nus.edu.sg/~pat/UTP2014/index.html ********************************************************************** CALL FOR PAPERS Interest in the fundamental problem of the combination of formal notations and theories of programming has grown consistently in recent years. The theories define, in various different ways, many common notions, such as abstraction, refinement, choice, termination, feasibility, locality, concurrency and communication. Despite these differences, such theories may be unified in a way which greatly facilitates their study and comparison. Moreover, such a unification offers a means of combining different languages describing various facets and artifacts of software development in a seamless, logically consistent way. Hoare and He's Unifying Theories of Programming (UTP) is widely acknowledged as one of the most significant such unification approaches. Based on their pioneering work, the aims of the UTP Symposium series are to reaffirm the significance of the ongoing UTP project and to stimulate efforts to advance. The Symposium provides a focus for the sharing of results by those already actively contributing, and raises awareness of the benefits of such unifying theoretical frameworks among the wider computer science and software engineering communities. To this end the Symposium welcomes contributions on all the themes that can be related to the Unifying Theories of Programming. SUBMISSIONS Papers may be up to 20 pages in length and should be prepared using LaTeX in Springer LNCS paper format. Submissions should be made through the UTP 2014 EasyChair site; instructions are at http://www.comp.nus.edu.sg/~pat/UTP2014 PUBLICATION Symposium post-proceedings will appear in Springer's Lectures Notes in Computer Science, as in past editions of the Symposium. (To be confirmed.) DATES Abstract due: January 17, 2014 Full paper due: January 24, 2014 Notification: March 7, 2014 Camera-ready for pre-proceedings: April 11, 2014 Symposium: May 12-13, 2014 CHAIR David Naumann (Stevens Institute of Technology) ORGANISATION CHAIR Jin Song DONG (National University of Singapore) PROGRAMME COMMITTEE Bernhard K.

Deadline extension for MSFP 2014
by Paul Levy 25 Dec '13

25 Dec '13

Please note extended deadlines: abstract 31 December and submission 7 January. -- Fifth Workshop on MATHEMATICALLY STRUCTURED FUNCTIONAL PROGRAMMING 12 April 2014, in Grenoble, France. A satellite workshop of ETAPS 2014 http://www.cs.bham.ac.uk/~pbl/msfp2014/ The fifth workshop on Mathematically Structured Functional Programming is devoted to the derivation of functionality from structure. It is a celebration of the direct impact of Theoretical Computer Science on programs as we write them today. Modern programming languages, and in particular functional languages, support the direct expression of mathematical structures, equipping programmers with tools of remarkable power and abstraction. Where would Haskell be without monads? Functional reactive programming without temporal logic? Call-by-push-value without adjunctions? The list goes on. This workshop is a forum for researchers who seek to reflect mathematical phenomena in data and control. The first MSFP workshop was held in Kuressaare, Estonia, in July 2006, affiliated with MPC 2006 and AMAST 2006. The second MSFP workshop was held in Reykjavik, Iceland as part of ICALP 2008. The third MSFP workshop was held in Baltimore, USA, as part of ICFP 2010. The fourth workshop was held in Tallinn, Estonia, as part of ETAPS 2012. Important Dates: ================ Abstract 31 December 2013, extended deadline Submission 7 January 2014, extended deadline Notification 3 February 2014 Final version 10 February 2014 Workshop 12 April 2014 Invited Speakers: ================= Bob Atkey Shin-ya Katsumata, Kyoto University Program Committee: ================== Andreas Abel, Chalmers and Gothenburg University Neil Ghani, University of Strathclyde Makoto Hamana, Gunma University Neelakantan R. Krishnaswami (co-chair), University of Birmingham Paul Blain Levy (co-chair), University of Birmingham Rasmus M??gelberg, IT University of Copenhagen Russell O'Connor, Google Canada Submission: =========== Papers must report previously unpublished work and not be submitted concurrently to another conference with refereed proceedings. Accepted papers must be presented at the workshop by one of the authors, and will be published under the auspices of EPTCS under a Creative Commons licence.

The description of Category 2 is now available in HTML5. http://members.shaw.ca/peasthope/Category2.html Each diagram is present in SVG, PNG and JPEG forms. The earlier document in XML, DOCTYPE XHTML 1.1 plus MathML 2.0 plus SVG 1.1, remains available. http://members.shaw.ca/peasthope/Category2.xhtml Eventually I'll drop it. Almost any browser in contemporary use will open the JPEG. The PNG images are Base64 encoded inside the primary document. Some browsers can display a PNG but are baffled by the Base64 encoding or the inline access. Windows XP, IE displays these JPEG and PNG but not the SVG or the MathML. A contemporary Firefox or Iceweasel displays all. Feedback is welcome. Thanks again to Fred Linton for suggesting the category and for comments.

ETAPS is an annual event which takes place in Europe each spring since 1998. The eighteenth conference, ETAPS 2015, will take place between April 11th and 19th, 2015 at Queen Mary University of London, in London, United Kingdom. London is one of the most visited and cosmopolitan cities on earth. It is a leading global city, with strengths in the arts, commerce, education, entertainment, fashion, finance, healthcare, media, professional services, research and development, tourism and transport all contributing to its prominence. It can be reached by more people, from more destinations, in less time, than any other destination in the world. ETAPS main conferences will take place on April 13th-17th, 2015. They are: - CC: International Conference on Compiler Construction - ESOP: European Symposium on Programming - FASE: Fundamental Approaches to Software Engineering - FOSSACS: Foundations of Software Science and Computation Structures - POST: Principles of Security and Trust - TACAS: Tools and Algorithms for the Construction and Analysis of Systems -- SATELLITE EVENTS -- The ETAPS 2015 organizing committee invites proposals for satellite events (workshops etc.) that will complement the main conferences. They should fall within the scope of ETAPS. This encompasses all aspects of the system development process, including specification, design, implementation, analysis and improvement, as well as the languages, methodologies and tools which support these activities, covering a spectrum from practically-motivated theory to soundly-based practice. Satellite events provide an opportunity to discuss and report on emerging research approaches and practical experience relevant to theory and practice of software. ETAPS 2015 satellite events will be held immediately before and after the main conferences, on April 11th-12th and April 18th-19th, 2015. -- ARRANGEMENTS FOR SATELLITE EVENTS -- The organizers of an ETAPS 2015 satellite are expected to: - create and maintain a website for the event, - form a PC, produce a call for papers for the event (if appropriate), - advertise the event through specialist mailing lists etc. to complement the publicity of ETAPS, - review the submissions received and make acceptance decisions, - prepare an informal (pre)proceedings for the event (if appropriate), - prepare the event's program complying with any scheduling constraints defined by the ETAPS 2015 organizing committee, - prepare and organize the publication of a formal (post)proceedings (if desired). The ETAPS 2015 organizing committee will: - promote the event on the website and in the publicity material of ETAPS 2015 - integrate the event's program into the overall program of the conference, - arrange registration for the event as a component of registration for ETAPS, collect a participation fee from the registrants, - produce a compilation USB memory stick of the informal (pre)proceedings of the satellite events of ETAPS 2015 and distribute this to the registrants, - provide the event with a meeting room of an appropriate size, A/V equipment, coffee breaks and possibly lunch(es). As a rule, ETAPS will not contribute toward the travel or accommodation costs of invited speakers or organizers of satellite events. -- SUBMISSION OF SATELLITE EVENT PROPOSALS -- Researchers and practitioners wishing to organize satellite events are invited to submit proposals in plain text or pdf by e-mail to Paulo Oliva p.oliva(a)qmul.ac.uk) A proposal should not exceed two pages and should include: - the name and acronym of the satellite event, - the names and contact information of the organizers, - the duration of the event: one or two days, - the preferred period: April 11-12th or April 18-19th, - a 120-word description of the event topic for the website and publicity material of ETAPS 2015, - a brief explanation of the event topic and its relevance to ETAPS - a tentative schedule for paper submission, notification of acceptance and final versions (the ETAPS 2015 organizing committee will need the final files for the local proceedings by March 13, 2015), - the plans for formal publication (no formal publication, formal proceedings ready by the event, formal post-proceedings), - the expected number of participants, - any other relevant information, like event format, invited speakers, demo sessions, special space requirements, etc. The proposals will be evaluated by the ETAPS 2015 organizing committee on the basis of their assessed benefit for prospective participants of ETAPS 2015. Prospective organizers may wish to consult the web pages of previous satellite events as examples: ETAPS 2014: http://www.etaps.org/2014/workshops ETAPS 2013: http://www.etaps.org/2013/workshops ETAPS 2012: http://www.etaps.org/2012/workshops ETAPS 2011: http://www.etaps.org/2011/workshops -- IMPORTANT DATES -- Satellite event proposals deadline: February 7th, 2014 Notification of acceptance: February 28th, 2014 -- FURTHER INFORMATION AND ENQUIRIES -- Please contact Paulo Oliva (p.oliva(a)qmul.ac.uk) [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
