I will explain how coisotropic submanifolds of symplectic
manifolds can be distinguished among all submanifolds by a
criterion ("local rigidity") related to the Hofer energy necessary
to disjoin open sets from them. This criterion is invariant
under...
In this talk, I'll discuss the role that Lie algebras play in
algebraic topology and motivate the development of a "homotopy
coherent" version of the theory. I'll also explain an
"equation-free" formulation of the classical theory of Lie
algebras...
