In this talk we will define a pseudo-Kähler structure on the deformation space of properly convex projective structures over the 2-dimensional torus.…

Slice knots: knot theory in dimension 4 – Paula Truöl (ETH Zürich)
Knot theory is a subarea of low-dimensional topology – the study of smooth manifolds of dimension 4 or less. Classical knots are smooth embeddings of the (oriented) circle S^1 into R^3 (or into the 3-sphere), usually studied up to an equivalence relation called ambient isotopy.…
Stably embedded ordered abelian groups – Pierre Touchard (Università degli Studi della Campania “Luigi Vanvitelli”)
It is well known that in a stable theory, all types are definable. In an unstable context, we can ask (like Cubides and Delon in [CD]) over which models $M$ of a given theory all types are definable. These models are exactly the models which are…

Long time behavior of solutions to open fluid systems – Eduard Feireisl (Institute of Mathematics, Czech Academy of Sciences)
We consider the physically relevant fully compressible setting of the Rayleigh-Benard problem of a fluid confined between two parallel plates, heated from the bottom, and subjected to the gravitational force. Under suitable restrictions imposed on…

Kashiwara crystals and the moduli space of stable rational curves – Leonid Rybnikov (HSE University, Faculty of Mathematics, Moscow)
The category of Kashiwara crystals for a semisimple complex Lie algebra $\mathfrak{g}$ is a combinatorial model of the tensor category of finite-dimensional $\mathfrak{g}$-modules, where $\mathfrak{g}$-modules are represented by colored oriented…
Searching for the impossible Azumaya algebra – Siddharth Mathur (Orsay)
In two 1968 seminars, Grothendieck used the framework of etale cohomology to extend the definition of the Brauer group to all schemes. Over a field, the objects admit a well-known algebro-geometric description: they are represented by…

On a general mixed dispersion nonlinear Schödinger equation – Pietro D’Avenia (Politecnico di Bari)
I will present a multiplicity result for a mixed dispersion nonlinear Schrödinger equation where the nonlinearity g satisfies general assumptions.…
