PhD graduated: Kristin Shaw (December 2011), Lionel Lang (December 2014), Nikita Kalinin (December 2015), Mikhail Shkolnikov (June 2017), Johannes Josi (February 2018).

Current members:Thomas Blomme, Weronika Czerniawska, Grigory Mikhalkin, Alina Pavlikova, Mikhail Pirogov.

Alumni: Ivan Bazhov, Johan Bjorklund, Rémi Crétois, Yi-Ning Hsiao, Jens Forsgard, Maxim Karev, Ilya Karzhemanov, Sergei Lanzat, Michele Nesci, Johannes Rau, Arthur Renaudineau.

We organize several seminars:

Séminaire "Fables Géométriques".

pre-2017 Battelle Seminar and

Tropical working group Seminar.

Also, you can check how tropical curves (and hypersurfaces, in general) emerge from abelian sandpile models: tropicalsand

Ilia Itenberg (Sorbonne)
Real enumerative invariants and their refinement
Salle 6-13, 14h15

Abstract:

The talk is devoted to several real and tropical enumerative problems. We suggest new invariants of the projective plane (and, more generally, of toric surfaces) that arise as results of an appropriate enumeration of real elliptic curves. These invariants admit a refinement (according to the quantum index) similar to the one introduced by Grigory Mikhalkin in the rational case. We discuss the combinatorics of tropical counterparts of the elliptic invariants under consideration and establish a tropical algorithm allowing one to compute them. This is a joint work with Eugenii Shustin.

Page creating is simple, just add internal link on non-existing page from existing.

For example еуые: .

Google “docuwiki …” to know how to do something if it is not clear.

Send me your nickname and password - to have right to create and edit pages.

Latex support is here. $\int \mathbb C + \prod\limits_{x\to \infty} f^g$
