In this paper we consider some properties of symmetric and skew-symmetric matrices over the max-plus algebra. These types of matrices have certain features that are valid in the conventional linear algebra but not in the linear algebra over the max-plus semiring, and vice versa. Taking this into account, we describe a new class of matrices over the max-plus algebra-the class of pseudo skew-symmetric matrices. Pseudo skew-symmetric matrices are square matrices with a zero diagonal whose symmetric elements cannot be negative at the same time. The basic properties of this class of matrices are introduced and proved in this study.
