CMSA Mathematical Physics Seminar: Networks and quantization


April 12, 2021      10:00 am
Speaker: Fei Yan - Rutgers University

I will describe two quantization scenarios. The first scenario involves the construction of a quantum trace map computing a link "invariant" (with possible wall-crossing behavior) for links L in a...

Aspects of M Theory


April 13, 2021      10:00 am
Speaker: Jens Hoppe - Technische Universitat Braunschweig

After giving a brief introduction to Membrane Theory and its matrix regularization, commenting on an inherent dynamical symmetry for all M-branes (the related “reconstruction-algebra” for M=1, strings, being the Virasoro algebra),...

Speaker: Claire Voisin - Collège de France

TITLE: K-theory and characteristic classes in topology and complex geometry (a tribute to Atiyah and Hirzebruch) ABSTRACT: We will discuss the K-theory of complex vector bundles on topological spaces and of holomorphic...

CMSA Quantum Matter in Mathematics and Physics: QCD without diagrams


April 15, 2021      10:30 am
Speaker: Michael Creutz - Brookhaven National Laboratory

QCD, the theory of the strong interactions, involves quarks interacting with non-Abelian gluon fields. This theory has many features that are difficult to impossible to see in conventional diagrammatic perturbation...

On the cohomology of moduli of abelian varieties


April 15, 2021      4:30 pm
Speaker: Melody Chan - Brown University

I’ll discuss recent work using tropical techniques to find new rational cohomology classes in moduli spaces A_g of abelian varieties, building on previous joint work with Galatius and Payne on M_g. I...
