Résumé: Combinatorial aspects of the Jacobi conjecture
Description: Axel de Goursac We expose the reformulation of the Jacobian conjecture in terms of the combinatorics of Feynman diagrams of a certain Quantum Field Theory. We will also discuss considerations about Dixmier conjecture and Noncommutative Quantum Field Theory.

Résumé: Some Results for Linear Logic Full Completeness
Description: Hugh Steele Many full completeness theorems have been established for fragments of
linear logic since the notion was first defined by Samson Abramsky and
Radha Jagadeesan in their 1992 paper. For the most part, these results
are obtained on a case-by-case basis: the subject of each proof is
precisely one category.

In this talk it is shown that the Hyland-Tan double glueing
construction can transform all tensor-generated compact closed
categories with finite biproducts into fully complete models of
unit-free MLL. The arguments employed are based around considering the
combinatorics behind the construction using standard linear algebra.
It is also discussed how another double glueing construction may be
able to create similar categories satisfying unit-free MALL full
