Open call for papers

Aimed at understanding the structure of mathematical proofs, proof theory has undergone different 
phases: it has been reductive, general, structural. Especially thanks to sequent calculus 
formalization, deep results were attained as far as proofs in pure logic and arithmetic are 
concerned. Through significant connections with computer science, proof theory contributed to 
the birth of new areas of research outside traditional mathematics, such as the verification of 
correctness of computer programs. Natural deduction has led to the Curry-Howard correspondence 
and to connections with functional programming, and sequent calculus is often used in systems of 
automatic proof search, as in logic programming. Rooted in general proof theory, a proof-theoretic 
semantics has been recently developed as an alternative to standard denotational truth-condition 
semantics. The workshop will focus mainly on proof systems, but we aim at touching several areas 
of the proof-theoretical research.

The workshop will be framed in two six-hour tutorials, six one-hour lectures, and is open to 
half-hour contributed talks. People interested to present a paper in the workshop may send a 
title with a short abstract to one of the following e-mail addresses:
