Call For Participation: Workshop "Proofs, Computation and Meaning"

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



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.



Extended registration deadline: 26 February 2020

Workshop: 20-21 March 2020
Warm-up for Master and PhD students: 19 March 2020



In addition to regular invited talks, the workshop includes two tutorials, aimed at introducing recent ideas on the correspondence between proofs, programs and categories as well as to the historical and philosophical aspects of the notions of infinity and predicativity.

If you wish to attend, please send an e-mail to luca.tranchini at or paolo.pistone at by 26 FEBRUARY.

A warm-up for master and PhD 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 warm-up will consists in two 2-hours lectures by the organizers).

There might be possibility to get ECTS credits for PhD students attending the workshop.



There will be a small registration fee (20 euros) covering both coffee breaks and the social dinner to be paid on arrival.
