O.Karpenkov (MSU-IUM, Moscow) "Energy of a knot".

There are several notions of knot energy.
The first such notion was introduced by Fukuhara in 1987
who proposed a method of untangling knots that makes use of
the gradient flow for the energy functional.
Subsequent authors, notably Ohara, Freedman--He--Wang,
Aaron-Cantarella-Fu-Ghomi-Howard and others considered different
definitions of knot energy.
I will speak about some new results related to the generalized 
energy of Aaron et al and a new construction that I call 
Min-Max energy.
