Promoting Scientific Activities

Scientific events organisation

Member of the organising committees

Yves Guiraud and Philippe Malbos organised with Samuel Mimram (LIX, École Polytechnique) the first edition of the Higher-Dimensional Rewriting and Applications (HDRA) workshop of the International Conference on Rewriting, Deduction, and Programming (RDP), held in Warsaw in June-July 2015. The second edition of HDRA will be held in June 2016 in Porto, during the new Formal Structures for Computation and Deduction (FSCD) conference.

Yann Régis-Gianas, Pierre Letouzey, Matthieu Sozeau were the organisers of the “Ecole de Printemps d'Informatique Théorique 2015” about proof of programs (cf. Highlights section).

Matthieu Sozeau co-organised and chaired the first Coq for Programming Languages (CoqPL) workshop, collocated with POPL’15 in Mumbai, India, in January 2015.
