\section{$\Z_2$-graded symmetry classes of tensors} By {\sl M. Shahryari}.  

\medskip  \noindent  In this paper, we define a natural $\Z_2$-gradation on the symmetry class of tensors $V_{\chi}(G)$. We give the dimensions of {\em even} and {\em odd} parts of this gradation. Also we prove that the even part ( the odd part) of this gradation is zero, if and only if the whole symmetry class is zero.
