Moscow Journal of Combinatorics and Number Theory publishes original, high-quality research articles from a broad range of interests within combinatorics, number theory and allied areas.

All of us, who work in the fields of mathematical informatics, in France and abroad, we will not forget him.
Philippe’s work accompanies us every day in our research and shows us the way.

Several members of SINFIN, notably in the ”Randomness and Analysis of Algorithms” team, worked hand by hand with Philippe Flajolet.

We meet virtually on Thursday, December 10th and Friday, December 11th for the STIC AMSUD meeting. The meeting will take place in the morning for the South Americans and in the afternoon for the French.

The schedule of the presentations is in the attached file with some
abstracts.

From February 23 to March 23, 2020, Martín Safe is visiting the GREYC Laboratory at Caen (France), and more particularly its AMACC team. He is invited on a “Chaire d’Excellence” inside the ALENOR Project, (a regional project between theuniversities of Caen, Rouen and Le Havre, Normandy).

The last week (16-22 March), he is invited at the CIRM (Centre international de Recherches Mathématiques, Marseille), for the Alea Journées of the GDR IM, and gives a talk on a joint work inside the SINFIN team (co-authored with Valérie Berthé, Eda Cesaratto, Frédéric Paccaut, Pablo Rotondo, Martin Safe, Brigitte Vallée)
