When: From Thursday, July 13 until Friday, July 14, 2023.
Venue: Faculty of Mathematics and Informatics, University of Barcelona: Gran Via de les Corts Catalanes, 585, 08007 Barcelona.
Overview:
The 5th International Workshop on Proof Theory and its Applications will take place the 13th and 14th of July 2023 in Barcelona, Spain, under the auspices of the Proof Society. The workshop will bring together researchers on proof theory and its applications through a programme based on invited and contributed talks aiming to fulfil the mission of The Proof Society:To support the notion of proof in its broadest sense, through a series of suitable activities; to be therefore inclusive in reaching out to all scientific areas which consider proof as an object in their studies; to enable the community to shape its future by identifying, formulating and communicating it most important goals; to actively promote proof to increase its visibility and representation.
We invite proposals for contributed talks at the workshop. These can be on published or unpublished work, as well as work in progress. The best talk presented by a student will receive an award from The Proof Society.
The Workshop will be co-located with the 5th Proof Society Summer School. The location of the Workshop is the historical building of the Faculty of Mathematics and Informatics which belongs to the Universitat de Barcelona, at the heart of the city.
Registration closes: June 26th, Extended to July 2th AoE.
Previous editions can be found at the Proof Society webpage.Programme:
Please download the workshop programme and schedule here.The duration of invited talks is expected to be 1 hour and the duration of contributed talks is expected to be 20 minutes, both including Q&A. There would be parallel sessions for the talks in rooms B5 and B6 of the Faculty of Mathematics and Informatics, University of Barcelona (see Contact & Travel Info).
