2-Local derivations on matrix rings over associative rings

Abstract

In the present paper it is proved that every inner 2-local derivation on the matrix ring $M_n(\Re )$ of $n\times n$ matrices over a commutative associative ring $\Re$ is an inner derivation. Also, it is proved that, every derivation on an associative ring $\Re$ has an extension to a derivation on the matrix ring $M_n(\Re )$ of $n\times n$ matrices over $\Re$.
