Workshop on Topology: Identifying Order in Complex Systems

Interactive visualization of 2-D persistence modules
5:00pm|S-101

In topological data analysis, we often study data by associating to the data a filtered topological space, whose structure we can then examine using persistent homology. However, in many settings, a single filtered space is not a rich enough...

Workshop on Topology: Identifying Order in Complex Systems

Hierarchical clustering on asymmetric networks
Facundo Mémoli
3:30pm|S-101

The problem of determining clusters in a data set admits different interpretations depending on whether the data is metric, symmetric but not necessarily metric, or asymmetric. Whereas there is a good degree of understanding of what are the natural...

Workshop on Topology: Identifying Order in Complex Systems

Topological and combinatorial methods in Theoretical Distributed Computing
Dmitry Feichtner-Kozlov
2:00pm|S-101

In the first half of the talk I will give a very compressed introduction into parts of Theoretical Distributed Computing from the point of view of mathematician. I will describe how to construct simplicial models whose combinatorics contains...

Workshop on Topology: Identifying Order in Complex Systems

Topological effects in metals: from chiral and gyrotropic magnetic effects to quenched Majoranas
Joel Moore
11:30am|S-101

The recent advances in our understanding of topological states of free-fermion insulators give some valuable concepts and tools for the analysis of metals. The first part of this talk focuses on low-energy electrodynamic responses of simple metals...

Workshop on Topology: Identifying Order in Complex Systems

Critical mechanical structures: topology and entropy
Xiaoming Mao
10:00am|S-101

Critical mechanical structures are structures at the verge of mechanical instability. These structures are characterized by their floppy modes, which are deformations costing little energy. On the one hand, numerous interesting phenomena in soft...

Joint IAS/Princeton University Symplectic Geometry Seminar

Negative and positive results in the intersection between systolic and symplectic geometry
Umberto Hryniewicz
2:00pm|S-101

How small is the smallest period of a closed trajectory of a Reeb flow? In this talk I will present recent answers to instances of this question in three-dimensions which reveal connections between systolic and symplectic geometry. I will present...
