ACTIVITIES AT THE GRADUATE CENTER
The seminars organized at the Graduate Center can be found here
weekly seminars bulletin.
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, 4:15pm5:15pm
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.

How large can Hardyweight be?
Abstract:
In the first part of the talk we will discuss the existence of optimal Hardytype inequalities with 'as large as possible' Hardyweight for a general secondorder elliptic operator defined on noncompact Riemannian manifolds and discrete graphs, while the second part of the talk will be devoted to a sharp answer to the question: "How large can Hardyweight be?"

Wild solutions for MHD models
Abstract:
We will discuss some wild behaviors exhibited by weak solutions of the magnetohydrodynamics with Hall effect and one of its limit cases. It includes lack of uniqueness of weak solutions in the LerayHopf class and construction of finite energy weak solutions that do not conserve magnetic helicity and magnetic energy.

Some convexity theorems of translating solitons in the mean curvature flow
Abstract:
I will be talking about the translating solitons (translators) in the mean curvature flow.
Convexity theorems of translators play fundamental roles in the classification of them.
Spruck and Xiao proved any two dimensional mean convex translator is actually convex.
Spruck and I proved a similar convex theorem for higher dimensional translators, namely the 2convex translating solitons are actually convex.
Our theorem implies 2convex translating solitons have to be the bowl soliton.
Our second theorem regards the solutions of the Dirichlet problem for translators in a bounded convex domain.
We proved the solutions will be convex under appropriate conditions.
This theorem implies the existence of n2 family of locally strictly convex translators in higher dimension.
In the end, we will show that our method could be used to establish a convexity theorem for constant mean curvature graph equation.
