Analysis Seminar: Tracial joint spectral measures
Speaker: Otte Heinävaara, Princeton University
Abstract: Given two Hermitian matrices, we introduce a new type of spectral measure, a tracial joint spectral measure on the plane. Existence of this measure implies that any two-dimensional subspace of the Schatten-p class is isometric to a subspace of L_p. We discuss some applications and limitations of this result.
