Workshop on Topology: Identifying Order in Complex Systems

Geometries of sensor outputs, inference, fusion and information processing
Ronald Coifman
11:00am|Hill Center 705, Rutgers University

Our goal is to describe extensions of the main tools of signal processing, denoising feature extraction, prediction, regression, to deal with more general data sources such as heterogeneous nonlinearly correlated multisensor inputs, questionnaires...

Workshop on Topology: Identifying Order in Complex Systems

Topological order: umbilics in chiral liquid crystals
Gareth Alexander
9:30am|Hill Center 705, Rutgers University

Recent experimental advances have opened the door to laboratory realisations of a large range of complex textures with distinctive topological properties, including knots, skyrmions and “Hopf fibrations” in optics, fluids, helical magnets and liquid...

Joint IAS/Princeton University Symplectic Geometry Seminar

Equivariant structures in mirror symmetry
1:30pm|S-101

When a variety \(X\) is equipped with the action of an algebraic group \(G\), it is natural to study the \(G\)-equivariant vector bundles or coherent sheaves on \(X\). When \(X\) furthermore has a mirror partner \(Y\), one can ask for the...

Joint IAS/Princeton University Number Theory Seminar

On the unipotent contributions of the Arthur-Selberg trace formula for \(\mathrm{GL}(n)\)
4:30pm|Fine 214, Princeton University

The Arthur-Selberg trace formula is a powerful tool in the theory of automorphic forms. Roughly speaking, it expresses the character of the regular representation on the automorphic spectrum in terms of distributions indexed by conjugacy classes...
