Speaker: Justin Malestein (University of Oklahoma)
Title: Rigid structures with symmetry
Justin Malestein will discuss questions and problems concerning the rigidity of bar-joint frameworks as well as rigidity of other kinds of combinatorial structures. One fundamental question is whether, given a graph (or other appropriate combinatorial description), a “generic” framework with that underlying graph is rigid. In some circumstances, however, one would like to understand the rigidity of frameworks which have some symmetry and so are not fully generic. Justin will present some of the recent results in this direction as well as some of the difficulties and methods for proving such results.
