Joint IAS/PU Symplectic Geometry Seminar

Dynamic and Topological Aspects of Hamiltonian Floer Theory on Surfaces
Dustin Connery-Grigg
1:00pm|Fine Hall 401

Given a Hamiltonian $H \in C^\infty(S^1 \times M)$, what is
the relationship between the dynamics of the isotopy generated by $H$
and the various Floer-theoretic invariants associated to $H$? In this
talk I will discuss how — in the case where $M$ is a...

Computer Science/Discrete Mathematics Seminar II

Simulating Time With Square-Root Space (And With Details)
Ryan Williams
10:30am|Rubenstein Commons | Meeting Room 5

We will go in-depth into the proof that for all functions $t(n) \geq n$, every multitape Turing machine running in time $t$ can be simulated in space only $O(\sqrt{t \log t})$. We will attempt to be completely self-contained. To that end, we will...

Joint IAS/PU Arithmetic Geometry

de Rham Cohomology of Holonomic D-modules
Feliks Raczka
3:30pm|Princeton University, Fine Hall 224

The talk will be devoted to the problem of finiteness of the de Rham cohomology of holonomic D-modules, with the emphasis on the nonarchimedean setting. First, I will briefly recall what holonomic D-modules are and why they are important. Next, I...
