First CfP: Workshop "Proofs, Computation and Meaning"

University of Tübingen (Germany), March 20-21 2020


*******************************************************************************

SCOPE:

Around thirty years after the fall of Hilbert's program, the proofs-as-programs paradigm established the view that a proof should not be identified, as in Hilbert's metamathematics, with a string of symbols in some formal system. Rather, proofs should consist in computational or epistemic objects conveying evidence to mathematical propositions. The relationship between formal derivations and proofs should then be analogous to the one between words and their meanings.


This view naturally gives rise to questions such as “which conditions should a formal arrangement of symbols satisfy to represent a proof?” or “when do two formal derivations represent the same proof?". These questions underlie past and current research in proof theory both in the theoretical computer science community (e.g. categorical logic, domain theory, linear logic) and in the philosophy community (e.g. proof-theoretic semantics).

In spite of these common motivations and historical roots, it seems that today proof theorists in philosophy and in computer science are losing sight of each other. This workshop aims at contributing to a renaissance of the interaction between researchers with different backgrounds by establishing a constructive environment for exchanging views, problems and results.

*******************************************************************************

SUBMISSIONS:

We invite submissions for contributed talks on topics related to the themes of the meeting. These include, but are not restricted to:

- Identity of proofs
- Graphical/diagrammatic representations of proofs
- Typed vs untyped proof theory
- Paradoxes and circular reasoning
- Constructivism and (im)predicativity
- Duality proofs/refutations
- Computational interpretations of classical and non-classical logics
- Non-deterministic/probabilistic aspects of computation
- Inductive/co-inductive constructions in proof theory and type theory
- (Higher-)categorical proof theory
- Substructural aspects of logic
- Philosophical and historical reflections on any of the above

Submissions should consist in a 1-2 pages extended abstract and should be sent to luca.tranchini at gmail.com or paolo.pistone at uniroma3.it by 15 JANUARY 2020.


*******************************************************************************

CALL FOR PARTICIPATION:

We strongly encourage Master and PhD students in any related area to participate and to apply for a limited number of travel grants.

Warm-up tutorials for students introducing the proofs-as-programs correspondence between proof theory and type theory will be organized on 19 March, the day before the start of the workshop. The detailed program of the tutorials will follow.

Also, there might be possibility to get ECTS credits for PhD students.

Travel grant applications must include a 1-page motivation letter and a cv and must be sent to luca.tranchini at gmail.com or paolo.pistone at uniroma3.it by 15 JANUARY 2020.


*******************************************************************************

REGISTRATION:

Registration is mandatory and will open in due time. There will be a small registration fee (20 euros) covering both coffee breaks and the social dinner.
