Final CfP: Workshop "Proofs, Computation and Meaning"
University of Tübingen (Germany), 20-21 March 2020
http://ls.informatik.uni-tuebingen.de/PCM/
*******************************************************************************
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.

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.
Tutorials:

- Noam Zeilberger (University of Birmingham)
Regular speakers:
- Bahareh Afshari (University of Gothenburg)
- Federico Aschieri (TU Vienna)
- Gilda Ferreira (Universidade Aberta, University of Lisbon)
- Dominic Hughes (UC Berkeley)
- Alberto Naibo (Paris 1 University)
- Gabriel Scherer (INRIA, Saclay)
*******************************************************************************
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 [email protected] or [email protected] by 15 JANUARY 2020.
*******************************************************************************
CALL FOR PARTICIPATION AND TRAVEL GRANTS:
If you wish to attend without giving a talk, please send an e-mail to
[email protected] or [email protected].
To encourage the participation of Master and PhD students we offer a limited
number of travel grants.
Moreover, a warm-up 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).
Finally, there might be possibility to get ECTS credits for PhD students
attending the workshop.
Travel grant applications must include a 1-page motivation letter and a cv and
must be sent to [email protected] or [email protected] by 15
JANUARY 2020.
*******************************************************************************
REGISTRATION:
There will be a small registration fee (20 euros) covering both coffee breaks
and the social dinner to be paid on arrival.
