Parallel Subtraction of Matrices

Abstract

A new Hermitian semidefinite matrix operation is studied. This operation—called parallel subtraction—is developed from the theory of parallel addition. Since the theory of parallel addition is motivated by the analysis of interconnected electrical networks, parallel subraction may be interpreted in terms of the synthesis of electrical networks. The idea of subtraction is also extended to hybrid addition.
