Infimum of a matrix norm of A induced by an absolute vector norm (2104.00072v2)

Published 31 Mar 2021 in math.FA

Abstract: We characterize the infimum of a matrix norm of a square matrix A induced by an absolute norm, over the fields of real and complex numbers. Usually this infimum is greater than the spectral radius of A. If A is sign equivalent to a nonnegative matrix B then this infimum is the spectral radius of B.
