| 15:30 - 17:00 Geometry and Topology Weekly Seminar What is GIT? School MATHEMATICS Actions of algebraic groups appear in many problems of Algebraic Geometry, encoding certain symmetries. Often one is interested in factoring out these symmetries and producing a new geometric object, a so-called quotient that parametrises the orbits of the action. In this framework, Geometric Invariant Theory (GIT) developed by David Mumford in 1965 deals with the problem of the existence of quotients, with an algebro-geometric structure, of an algebraic variety by the action of a reductive group. This method is extremely useful which also has important and surprising connections with symplectic geometry. In this lecture we shall give a gent ... 17:30 - 18:30 Number Theory Seminar Non-vanishing of L-functions at the central point School MATHEMATICS I will talk about two methods used to derive non-vanishing results for a family of L-functions; the one-level density and the moments of L-functions. I will mention what these methods are and how they are used to get non-vanishing.
