On Translated Points of Contactomorphisms
Sheila Margherita Sandon
4:00pm|S-101

The Arnold conjecture in Symplectic Topology states existence of many fixed points for Hamiltonian symplectomorphisms of a compact symplectic manifold. In my talk I will discuss an analogue of this conjecture in Contact Topology, based on the notion...

Reducibility for the Quasi-Periodic Liner Schrodinger and Wave Equations
Lars Hakan Eliasson
2:30pm|S-101

We shall discuss reducibility of these equations on the torus with a small potential that depends quasi-periodically on time. Reducibility amounts to "reduce” the equation to a time-independent linear equation with pure point spectrum in which case...

Computer Science/Discrete Mathematics Seminar I

Lasserre Hierarchy, Higher Eigenvalues, and Graph Partitioning
Venkat Guruswami
11:15am|S-101

Partitioning the vertices of a graph into two (roughly) equal parts to minimize the weight of edges cut is a fundamental optimization problem, arising in diverse applications. Despite intense research, there remains a huge gap in our understanding...

Arithmetic Fake Compact Hermitian Symmetric Spaces
4:30pm|S-101

A fake projective plane is a smooth complex projective algebraic surface whose Betti numbers are same as those of the complex projective plane but which is not the complex projective plane. The first fake projective plane was constructed by David...
