PROBMIV'99: Call for Participation
by Marta Z Kwiatkowska 26 Jun '99

26 Jun '99

[Please circulate this to anyone interested. Apologies for multiple copies.] _________________________________________________________________________ CALL FOR PARTICIPATION PROBMIV'99 2nd International Workshop on Probabilistic Methods in Verification http://fmt.cs.utwente.nl/probmiv99/ a satellite to CONCUR'99 Eindhoven, 23rd Aug 1999 (to coincide with EXPRESS'99, another satellite) >>>>>>>>>>>EARLY REGISTRATION FOR CONCUR ENDS 1st JULY<<<<<<<<<<<<<<<<<<< _________________________________________________________________________ SCOPE OF THE WORKSHOP Probability inherently features in software and hardware systems, either as a means to derive efficient solutions (e.g. randomization), or as a result of unreliable or unpredictable behaviour (e.g. fault-tolerant systems, computer networks, etc). *Probabilistic verification* encompasses a range of theoretical, algorithmic and programming methods that assist in establishing the correctness of probabilistic systems against specifications. Typically this involves calculating the probability bounds for a temporal logic formula being satisfied, based on an appropriate probability space on computations, but also includes properties such as cost analysis and long-run average. Additionally, probabilistic verification can provide guarantees the specifications hold with satisfactory probability in cases when conventional model checking is not feasible. The idea of this workshop is to bring together researchers that apply probabilistic methods across the whole spectrum of verification. The meeting aims to enable cross-fertilisation of ideas and techniques between areas that are usually not in regular contact through conferences, from semantics, probability theory, performance analysis and computational linear algebra, through randomized algorithms, probabilistic logics, model checking, abstract interpretation, to practical experimental work, tools and applications. This is the second workshop of this kind. The first meeting, PROBMIV'98 was held in 1998 as a satellite to LICS. In 1999, the workshop takes place as a satellite to CONCUR. _________________________________________________________________________ INVITED PAPERS Rance Cleaveland, SUNY at Stony Brook: Probabilistic Model Checking via the Modal Mu-Calculus Bengt Jonsson, University of Uppsala: On Model Checking Infinite-State Probabilistic Systems Kim Larsen, Aalborg University: Testing and Verification of Probabilistic Systems Oded Maler, Verimag: On the Representation of Probabilities over Structured Domains _________________________________________________________________________ ACCEPTED CONTRIBUTIONS Christel Baier, University of Mannheim, and Holger Hermanns, University of Twente: A lazy synchronous calculus of fully probabilistic processes Luca de Alfaro, University of California at Berkeley: The Verification of Probabilistic Systems under Memoryless Partial-Information Policies is Hard Josee Desharnais, McGill University: A logical characterization of probabilistic simulation Alessandra Di Pierro, University of Pisa, and Herbert Wiklicky, Imperial College: Ergodic Average in Constraint Programming Manfred Jaeger, Max-Planck-Institut at Saarbrucken: Fairness, Computable Fairness and Randomness Jeremy Sproston, University of Birmingham: Analysing subclasses of probabilistic hybrid automata _________________________________________________________________________ STEERING AND PROGRAM COMMITTEE Rajeev Alur, University of Pennsylvania Christel Baier, University of Mannheim Luca de Alfaro, University of California at Berkeley Michael Huth, Kansas State University Joost-Pieter Katoen, University of Twente Marta Kwiatkowska, University of Birmingham (chair) Roberto Segala, University of Bologna Prakash Panangaden, McGill University _________________________________________________________________________ RELATED EVENTS PROBMIV'99 is organized as a satellite workshop of CONCUR'99, the 10th International Conference on Concurrency Theory, which will take place in Eindhoven on August 24-27, 1999.

Announcement WD'99
by Thomas Streicher 24 Jun '99

24 Jun '99

Sorry, if you receive this announcement several times ! 2nd Announcement of 5th DOMAINS WORKSHOP (Darmstadt, 23. - 26. September 1999) Dear colleagues, the 5th Workshop on Domains will take place in Darmstadt from Thursday, the 23rd of September till Sunday, the 26th of September. We will start on Thursday after lunch. In this session there will be talks by D.Scott and A.Jung on the occasion of Klaus Keimel's 60th Birthday. Afterwards, there will be a football match in the early evening followed by a barbecue. Whether there will be program on Sunday or it will be the day of departure will depend on the number of talks that people want to deliver. The idea of having in principle two full days for talks is motivated mainly by the intention to avoid a too dense schedule and leave enough time for discussion. The talks should concentrate on the following topics - Classical Domain Theory - Denotational Semantics of Programming Languages - Categorical Logic and Realisability - Synthetic Domain Theory - Non-Classical Domain Theory (Stable Domains, Full Abstraction ...) - Exact Computation on Classical Spaces This list is not exclusive and talks on related topics are encouraged. As usual there will be "open house" in the sense that there is no refereeing and people are invited to talk about work in progress. For registration, please, send a message to marz(a)mathematik.tu-darmstadt.de together with title and abstract of your talk. If you want to give a talk you have to tell us till 23rd August 1999. More information about the workshop can be found at the homepage http://www.mathematik.tu-darmstadt.de/~erker/wd5/ In particular, there you can find an address via which you can reserve accommodation. We also plan to organise some private accommodation for undergraduate students who cannot afford to pay the hotel expenses. Awaiting your registration Michael Marz, Thomas Streicher

HHA article available
by Walter Tholen 24 Jun '99

24 Jun '99

The following paper is now available: A Categorical Guide to Separation, Compactness and Perfectness Walter Tholen Based on a rather arbitrary class of morphisms in a category, which play the role of "closed maps", we present a general approach to separation and compactness, both at the object and the morphism levels. It covers essential parts of the classical topological theory, generalizes various previous categorical treatments of the theme, and allows for a number of less expected applications outside topology.

preprint: Representable Multicategories
by Claudio Hermida 22 Jun '99

22 Jun '99

The preprint `Representable multicategories' is available at http://www.maths.usyd.edu.au:8000/u/hermida Abstract: We introduce the notion of representable multicategory, which stands in the same relation to that of monoidal category as fibration does to contravariant pseudofunctor (into Cat). We give an abstract reformulation of multicategories as monads in a suitable Kleisli bicategory of spans. We describe representability in elementary terms via universal arrows. We also give a doctrinal characterisation of representability based on a fundamental monadic adjunction between the 2-category of multicategories and that of strict monoidal categories. The first main result is the coherence theorem for representable multicategories, asserting their equivalence to strict ones, which we establish via a new technique based on the above doctrinal characterisation. The other main result is a 2-equivalence between the 2-category of representable multicategories and that of monoidal categories and strong monoidal functors. This correspondence extends smoothly to one between bicategories and a localised version of representable multicategories. -- Claudio Hermida School of Mathematics and Statistics F07, University of Sydney, Sydney, NSW 2006, Australia

"OctoberFest" category theory meeting in Montreal
by Robert A.G. Seely 21 Jun '99

21 Jun '99

Centre de Recherche en Theorie des Categories -- Montreal -- Category Theory Research Center ----------------------------------------------------------------------------- Category Theory OctoberFest McGill University, Montreal Saturday - Sunday, October 16 - 17, 1999 ----------------------------------------------------------------------------- We invite you to join us in Montreal next October for a weekend meeting in Category Theory, the "not-quite-annual" OctoberFest. As has been the tradition with these meetings, we invite talks from all participants. If you wish to give a talk, send your request along with a short abstract (before the end of September please) to Robert Seely at the address below. Early in October the program committee will announce a preliminary schedule on the Categories email list, and on the CTRC/CRTC web site. The final schedule will be announced at the meeting. We will meet in the Bronfman Building, 1001 Sherbrooke West, on Saturday morning, October 16th. Coffee will be available from 8:30 am. The first talk will be at 9:00. Registration will take place during the morning, before the first talk and during the first coffee break. There will be a registration fee of about $CAN45 (approximately $US30), with luck, less: all possible attempts will be made to keep this as low as we can. The precise amount will be announced in early October, along with the proposed schedule. There will be a dinner/party to be held Saturday evening, hosted by Marta Bunge. (Instructions for getting to the Bunge home will be announced at the meeting.) Please let us know if you intend to join us by sending a short email (before the end of September if possible) to Robert Seely, also indicating whether or not you will bring a guest to the party. (We need to have a good estimate of how many people will attend the party about a week before the meeting.) Below you will find a list of hotels and tourist rooms close to McGill. Please note that October is a popular month for visiting Montreal, and early booking is recommended. If you have any further questions, please contact one of us. -------------------------------------------------------------------------------- Michael Barr [barr(a)barrs.org] Robert Seely [rags(a)math.mcgill.ca] Dept of Mathematics and Statistics McGill University 805 Sherbrooke West Montreal, Quebec CANADA H3A 2K6 -------------------------------------------------------------------------------- Hotels: (Montreal area code = 514) * L'Appartement, 455 Sherbrooke W, 284-3634, $85 * Howard Johnson Plaza, 475 Sherbrooke W, 842-3961, $94 (1-800-842-3961).
