Title:
Hadamard powers of positive matrices

Abstract of Talk

Entrywise functions that preserve the cone of positive semidefinite matrices have been extensively studied. Among them, the power functions, called Hadamard powers, are of special interest due to their applications in probability and statistics. In this talk, we discuss some fundamental results about the Hadamard powers of positive matrices.
