ACTIVITIES AT THE GRADUATE CENTER

Here is the list of seminars organized at the Graduate Center weekly seminars bulletin (updated every Tuesday).
Here, you will find the conferences in nonlinear analysis we are organizing at the Graduate Center.

Nonlinear Group Study

This meeting aims to investigate nonlinear problems arising in Differential geometry and mathematical physics. It gives graduates students the opportunity to be familiar with a wide range of open problems, and learn tools from the calculus of variations to tackle some of these questions. Our meeting takes place

Goals of these seminars is to discuss techniques that are used nonlinear problems arising in applied mathematics,physics or differential geometry. These events are sponsored by the Initiative for the Theoretical Sciences.

Those participating in the Nonlinear Analysis and PDE seminar may also be interested in the Geometric Analysis Seminar which meets also on Thursdays in the same room 6496 starting at 3pm.

  Morse theory and the resonant $Q$-curvature problem
  Abstract: The Q-curvature is a scalar quantity which plays a central role in conformal geometry, in particular in the search of high order conformal invariants. In this talk we address the problem of finding conformal metrics of prescribed Q-curvature on four riemannian manifolds in the so called resonant case, that is when the total integral of the Q-curvature is a multiple of the one of the four-dimensional round sphere. This geometric problem has a variational structure with a lack of compactness. Using some topological tools of the theory of critical points at infinity of Abbas Bahri, combined with a refined blow-up analysis, we extend the full Morse theory, including Morse inequalities, to this non-compact geometric variational problem and derive existence and multiplicity results. This is a joint work with C.B. Ndiaye (Howard University)
