Title: On variational formula of moduli of Riemann surfaces
Abstract: The seminar aims at deriving the variational formulas of moduli of Riemann surface as obtained in the articles “ Rauch, H. E. Weierstrass points, branch points, and moduli of Riemann surfaces. Comm. Pure Appl. Math. 12 1959, 543–560” and "Kokotov, A.; Korotkin, D. Tau-functions on Hurwitz spaces. Math. Phys. Anal. Geom. 7 (2004), no. 1, 47–96.
15.00-16.00

Title: Forced lattice vibration
Abstract: The Toda lattice with zero boundary conditions and driven from one end will be considered. It will be shown that an ample family of travelling wave solutions exist.
The talk is based on the paper :Deift, Percy; Kriecherbauer, Thomas; Venakides, Stephanos Forced lattice vibrations. I, II. Comm. Pure Appl. Math. 48 (1995), no. 11, 1187–1249, 1251–1298.
