The copositive matriz problem

摘要：

An n×n real symmetric matrix A is called (strictly) copositive if xT Ax ≥ 0 (> 0). In this paper, make use of Gerschgorin theorem and the properties of copositive matrix, we give a sufficient condition and a necessary condition with the determination of the copositive matrix, and we also give a better completion with the theorem 6 in paper 3. A better and easier determination for examples in paper 6.
