Let $V$ be a unitary vector space. Suppose $G$ is a permutation group of degree $m$ and $\Lambda$ is an irreducible unitary representation of $G$. We denote by $V_{\Lambda}(G)$ the generalized symmetry class of tensors associated with $G$ and $\Lambd

In this paper, the problem existing $O$-basis for Cartesian symmetry classes is discussed. The dimensions of Cartesian symmetry classes associated with a cyclic subgroup of the symmetric group $S_m$ (generated by a product of disjoint cycles) and the

In this paper, we give a necessary and sufficient condition for the equality of two symmetrized decomposable polynomials. Then, we study some algebraic and geometric properties of the induced operators over symmetry classes of

Let $G_{i} $ be a subgroup of $ S_{m_{i}} , 1 leq i leq k$. Suppose $chi_{i}$ is an irreducible complex character of $G_{i}$. We consider $ G_{1}times cdots times G_{k} $ as subgroup of $ S_{m} $, where $ m=m_{1}+cdots +m_{k} $. In this paper, we giv
