+**Diagonal bases and wall-crossings in moduli spaces of vector bundle**
+The idea  of the calculation of the Hilbert function of the moduli spaces of vector bundles on Riemann surfaces goes back to the works of Michael Thaddeus in the early 90’s.
+I describe joint work with Olga Trapeznikova where this plan is carried out in detail, which uses only basic tools of Geometric Invariant Theory and a combinatorial/analytic device introduced by myself: the diagonal basis of hyperplane arrangements.

+**Markov numbers in number theory, topology, algebraic geometry, and differential equations**
+I will explain how the Markov numbers arise in different mathematical
+disciplines, and sketch the links. A recent contribution will be discussed, too.
