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
Nonlinear Analysis and PDEs
CUNY Graduate Center, 365 Fifth Avenue, NYC
Room 6496, 4:15pm--5:15pm
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
The Q-curvature is a scalar quantity which plays a central role in
conformal geometry, in particular in the search of high order
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)
