Barcodes and $C^0$ symplectic topology
Hamiltonian homeomorphisms are those homeomorphisms of a
symplectic manifold which can be written as uniform limits of
Hamiltonian diffeomorphisms. One difficulty in studying Hamiltonian
homeomorphisms (particularly in dimensions greater than two)...
Two questions of Landis and their applications
We discuss two old questions of Landis concerning behavior of
solutions of second order elliptic equations. The first one is on
propagation of smallness for solutions from sets of positive
measure, we answer this question and as a corollary prove an...
Nearby cycles over general bases and duality
Weizhe Zheng
Over one-dimensional bases, Gabber and Beilinson proved theorems
on the commutation of the nearby cycle functor and the vanishing
cycle functor with duality. In this talk, I will explain a way to
unify the two theorems, confirming a prediction of...
How to detect a projective space?
In 1984, Robert Lazarsfeld solved an old conjecture of Remmert
and Van de Ven, which stated that there are no non-trivial complex
manifolds that can be covered by a projective space. His result was
a consequence of Shigefumi Mori's breakthrough...
Non-accumulation of periodic torus orbits
The "linearization" technique is a powerful method in
homogeneous dynamics to control the time a unipotent orbit spends
in the vicinity of a closed homogeneous subset. This method relies
on the polynomial nature of a unipotent flow and does not...
