Analysis Seminar

Three Projection Operators in Several Complex Variables
Elias Stein
3:15pm|S-101

I will report on recent joint work with L. Lanzani on three basic projection operators, each associated to an appropriate domain in C^n. These are: variants of Cauchy-Fantappie integrals; the Cauchy-Szego projection: and the Bergman projection. The...

Joint IAS/Princeton University Symplectic Geometry Seminar

Behavior of Welschinger Invariants Under Morse Simplification
Erwan Brugalle
2:00pm|S-101

Welschinger invariants, real analogs of genus 0 Gromov-Witten invariants, provide non-trivial lower bounds in real algebraic geometry. In this talk I will explain how to get some wall-crossing formulas relating Welschinger invariants of the same (up...

Joint IAS/Princeton University Number Theory Seminar

The Tate Conjecture for K3 Surfaces Over Fields of Odd Characteristic
Keerthi Madapusi
4:30pm|Fine Hall 214

The classical Kuga-Satake construction, over the complex numbers, uses Hodge theory to attach to each polarized K3 surface an abelian variety in a natural way. Deligne and Andre extended this to fields of characteristic zero, and their results can...

Workshop on Topology: Identifying Order in Complex Systems

Membranes, Curvature and the Endoplasmic Reticulum
Greg Huber
4:00pm|David Rittenhouse Lab.(Room A8), University of Pennsylvania

"I seemed to see the membraneous and cylindrical tubes tremble beneath the undulation of the waters." - Jules Verne (describing Captain Nemo's underwater garden in 20,000 Leagues Under the Sea) For over half a century, microscopists have seemed to...

Workshop on Topology: Identifying Order in Complex Systems

Dynamic Programming for ab-initio Prediction of Protein Folding Routes
Julia Hockemaier
2:30pm|David Rittenhouse Lab.(Room A8), University of Pennsylvania

I will demonstrate how the Cocke-Kasami-Younger (CKY) algorithm, a standard dynamic programming technique that is normally used in natural language parsing, can be adapted to give us novel insights into the protein folding problem. If we assume that...
