Seminar

The Graphs and Networks seminar will meet Mondays at 9:30 am via Microsoft Teams.
Greg Constantine will start by giving 3 talks on classification attempts of graphs of maximal complexity. The triangle-free strongly regular graphs -- all subgraphs of the Higman-Sims graph -- are proved to be instances of such graphs of maximal complexity. A series of conjectures and some stubborn research issues will be brought to attention.

Jon Rubin will then give several talks on networks. Sevak Mkrtchyan will also present a series of talks.

In this talk, we shall present a gravitational vacuum Hamiltonian other than Schwarzschild that is invariant under SU(2), the spin group of the three-dimensional rotation group, based on the sub-Riemannian structure on the three-sphere.  We will also discuss the structure of its null geodesics.
 

Starting in 2021, the University of Pittsburgh AWM Chapter hosts the Pitt AWM Student Seminar Series, held on the first Fridays of each month at 4:45pm. Every meeting features two 30 minute long talks by female PhD students, each presenting the speaker's research outcomes. Our seminar is hoped to give a platform to female students-researchers, to promote the spirit of collegiality and collaboration, and to recognize the hard work of students during this pandemic time.
