The cutwidth problem for a graph G is to embed G into a path such that the maximum number of overlap edges is minimized. This paper presents an approach based o
Abstract. A matrix whose entries are +, -, and 0 is called a sign pattern matrix. For a signpattern matrix A,if A3 =A, then A is said to be sign tripotent. In t
The existence and uniqueness results about quasilinear periodic boundary value problems are established by using the global inverse function theorem and the res
