Math Seminar: Unitary Orbit Preservers
Thursday, November 14, 2019
2:00 PM-3:00 PM
Edward Poon, Embry-Riddle Aeronautical University
Abstract: Given an operator A acting on a Hilbert space H and a group G of unitary operators on H, the unitary orbit of A under G is {UAU*: U in G}. We discuss the problem of characterizing the linear maps which leave this orbit invariant for various choices of A and G.
