IAS/Princeton/Montreal/Paris/Tel-Aviv Symplectic Geometry Zoominar

Markov Staircases
Joé Brendel
9:15am|Remote Access

In this talk, we will discuss new infinite symplectic staircases. Much recent progress has been made in the study of infinite symplectic staircases arising from embedding problems of standard ellipsoids into various symplectic four-manifolds. We...

Aspects of Membrane Theory
Jens Hoppe
11:00am|Bloomberg Lecture Hall (IAS) & Zoom

Abstract: Mostly concerning Lorentz-invariance and the matrix-approximation of membranes ( GH1982: http:/dspace.mit.edu/handle/1721.1/15717, G1985, BFFS1997: Phys.Rev.D 55, 5512 ), as well as non-commutative string-theory ( JH1996: hep-th/9602020...

Why Extension-Based Proofs Fail
Faith Ellen
10:30am|Simonyi Hall 101 and Remote Access

A valency argument is an elegant and well-known technique for proving impossibility results in distributed computing. It is an example of an extension-based proof, which is modelled as an interaction between a prover and a protocol. Even though...

Flow Categories as Exit Path Categories
Colin Fourel
1:00pm|Simonyi 101 and Remote Access

Given a Morse function on a closed smooth manifold and a Smale gradient-like vector field adapted to it, one can construct a topological category called the flow category associated with this data. Its objects are the critical points of the function...

Special Year Seminar I

Tropical Subrepresentations and Matroids
2:00pm|Simonyi 101

In their recent paper, Giansiracusa and Manaker introduced a notion of tropical subrepresentations of linear representations by considering linear actions on tropical linear spaces. In particular, this framework naturally brings matroids into the...

Fourier-Mukai Transform for Tropical Abelian Varieties
Farbod Shokrieh
10:00am|Simonyi 101

I will present a (cohomological) Fourier-Mukai transform for tropical Abelian varieties and give some applications, including a (generalized) Poincaré formula (for non-degenerate line bundles on tropical Abelian varieties).

Based on joint work with...

Towards the HZ- and Multiplicity Conjectures for Dynamically Convex Reeb Flows
Basak Gurel
9:15am|Remote Access

In this talk we discuss the multiplicity question for prime closed orbits of a dynamically convex Reeb flow on the boundary of a $2n$-dimensional star-shaped domain. Our first main result asserts that such a flow has at least n prime closed Reeb...
