Abstract:
The algebra $M_n(F)$ of all $n\times n$ matrices over a field $F$ has a natural $\mathbf {Z}_n$-grading $M_n(F)=\sum _{\alpha \in \mathbf {Z}_n}\bigoplus \mathcal {M}_n^{(\alpha )}$. In this paper graded identities of the $\mathbf {Z}_n$-graded algebra $M_n(F)$ over a field of characteristic zero are studied. It is shown that all the $\mathbf {Z}_n$-graded polynomial identities of $M_n(F)$ follow from the following: \[ x_1x_2-x_2x_1=0,~~~~\alpha (x_1)=\alpha (x_2)=\overline {0};\] \[ x_1xx_2-x_2xx_1=0,~~~~\alpha (x_1)=\alpha (x_2)=-\alpha (x).\]References
