On the unique solution of the generalized absolute value equation
share
In this paper, some useful necessary and sufficient conditions for the unique solution of the generalized absolute value equation (GAVE) Ax-B|x|=b with A, B∈R^n× n from the optimization field are first presented, which cover the fundamental theorem for the unique solution of the linear system Ax=b with A∈R^n× n. Not only that, some new sufficient conditions for the unique solution of the GAVE are obtained, which are weaker than the previous published works.
