Special Volume of MSCS in honor of Marek Zawadowski
by Chris Kapulkin 17 Mar '25

17 Mar '25

Dear Colleagues, We are honored to announce a special volume of the journal Mathematical Structures in Computer Science celebrating the work of Marek Zawadowski. Marek Zawadowski (1960-2024) was a mathematician at the University of Warsaw. He received his Ph.D. from the Université de Montréal in 1989 under the supervision of Gonzalo Reyes with the dissertation “Théorie de la descente pour les prétopos.” He made fundamental contributions to category theory, logic, and linguistics. He passed away unexpectedly in February 2024. This special volume is a celebration of Marek Zawadowski’s work and welcomes submissions on a broad range of topics, including: categorical logic, higher category theory, and linguistics. The volume will be edited by four guest editors: Pierre-Louis Curien (Université Paris Cité and Inria) Justyna Grudzińska (University of Warsaw) Chris Kapulkin (University of Western Ontario) Karol Szumiło (University of Warsaw) To submit your paper to the special volume, please go to https://mc.manuscriptcentral.com/mscs After starting a new submission, you will be asked (as part of Step 1) whether your manuscript is a candidate for a Special Issue; you should select “Tribute to Marek Zawadowski.” The editors will be happy to answer any questions at marek.zawadowski.memorial(a)gmail.com The submission deadline is March 31, 2025. If you are planning to submit a paper but are worried about making the deadline, please contact the editors at your earliest convenience. Best wishes, Chris Kapulkin For the Guest Editors You're receiving this message because you're a member of the Categories mailing list group from Macquarie University.

Two post-doc positions at Topos Research UK
by David Jaz Myers 01 Sep '24

01 Sep '24

Hi all, The Topos Institute is starting a UK branch in Oxford and we’re opening up two post-doc positions starting Oct 1, 2024. Topos is looking to grow our UK team, so while this position is currently funded by a 1-year project, selected candidates may have the opportunity for extension or even to transition into a permanent role. We’re looking for candidates with PhDs in category theory, type theory, algebraic systems theory, or related areas in mathematics and computer science who are interested in applying their knowledge to practical problems of scientific modelling. We’ll be working on compositional scientific modelling, model validation, and structure-aware version control. We’re hiring for two work projects: in the first, we’ll be developing double categorical systems theory, using monoidal double categories to organise the composition of systems and using monoidal double categories of spans or relations to organise the logic of system validation. In the second, we’ll be researching structure-aware version control (using type theory / logical relations and categorical patch theory) for the purpose of version controlling and incrementally updating scientific models. Please reach out to me with any inquiries or questions, and for more info, follow this link: https://topos.site/blog/2024-08-30-postdoc-job-openings-in-topos-oxford/ Cheers, David Jaz You're receiving this message because you're a member of the Categories mailing list group from Macquarie University.

2 year postdoc in Tallinn - application deadline 15 September
by Pawel Sobocinski 28 Aug '24

28 Aug '24

Dear all, I would like to advertise a two year postdoc starting on 1 January 2025 in the Compositionality group at the Tallinn University of Technology. The application deadline is 15 September 2024. The position would suit a category theorist interested in computer science, and especially in applications in probability theory, logic, verification and AI. The project is tied to the Estonian Center of Excellence in AI (EXAI) and the successful candidate will have the opportunity to get involved in several other exciting ongoing projects in Tallinn and Tartu. There is also a close thematic connection with the ARIA Safeguarded AI programme which is supporting two projects in the group that have closely aligned goals in developing categorical probability theory and diagrammatic reasoning. Applicants can apply at the link pasted below. Please do not hesitate to reach out to me with any questions.
