Generalized Cartesian Symmetry Classes

Abstract

Let $V$ be a unitary space. Suppose $G$ is a subgroup of the full symmetric group $S_{m}$ and $\mathfrak{X}$ is an irreducible unitary representation of $G$. In this paper, we introduce the generalized Cartesian symmetry class over $V$ associated with $G$ and $\mathfrak{X}$. Then we investigate some important properties of this vector space. Also, we study some basic properties of the induced linear operators on the generalized Cartesian symmetry classes. Some open problems are also given.
