B?hm Trees and Taylor Expansion are their two central paradigms, related by the Commutation Theorem. While these notions are well understood in Call-by-Name (CbN), they have only recently been developed for Call-by-Value (CbV). However, these notions require a separate development for each evaluation strategy of the ?-calculus, which motivates the search for a unified approximation framework. The Bang-calculus provides such a framework: it subsumes both CbN and CbV through linear-logic translations and enjoys robust rewriting properties. We develop the approximation semantics of dBang (the Bang-calculus with explicit substitutions and distant reductions) by introducing approximation trees in the B?hm tradition together with Taylor expansion. We establish their fundamental properties, including a commutation theorem. Via translations, our results recover the CbN and CbV setting within a single unifying framework capturing infinitary and resource-sensitive semantics.

We have 3 fantastic speakers followed by a hopefully lively discussion session about how to turn the event into something recurring. Lunch and coffee will be provided and is sponsored by SICSA. A website of the event can be found here https://msp.cis.strath.ac.uk/stpv2026/ Registration is free but required (for planning purposes). Registration can be done here: https://www.tickettailor.com/events/sicsa/2403747 by Wednesday 23 September. All the best, Clemens (on behalf of the SICSA Theory & Modelling theme) -------------- next part -------------- An HTML attachment was scrubbed...

Hope to see you there! Best wishes, Emma Date, time and place: Tuesday 29 September, 15:00, Livingstone Tower room LT619 Online attendance: https://www.youtube.com/@msp.strathclyde/streams Speaker: Fred Nordvall Forsberg (MSP) Title: Linear Logic Abstract: Linear logic, invented by Girard, is often said to be the 'resource conscious' logic: a proof in linear logic must use all of its hypothesis exactly once. This is achieved by dropping the structural rules of contraction (merging two copies of the same hypothesis) and weakening (introducing an unused hypothesis). Duality in the resulting sequent calculus suggests several new logical connectives, and so called exponentials, which bring back contraction and weakening in a control form. I will give a basic introduction to linear logic, not assuming the audience has seen sequent calculus before. There is a rich landscape of further topics that I probably will not have time to go into, such as call-by-name and call-by-value translations of intuitinistic logic into linear logic, categorical semantics in the form of monoidal categories, and linear type systems in programming.
