Abstract
We introduce the notion of endomorph \( E({\mathcal{A}}) \) of a \( ( \)super\( ) \)algebra \( {\mathcal{A}} \) and prove that \( E({\mathcal{A}}) \) is a simple \( ( \)super\( ) \)algebra if \( {\mathcal{A}} \) is not an algebra of scalar multiplication. If \( {\mathcal{A}} \) is a right-symmetric (super)algebra then \( E({\mathcal{A}}) \) is right-symmetric as well. Thus, we construct a wide class of simple (right-symmetric) (super)algebras which contains a matrix subalgebra with a common unity. We calculate the derivation algebra of the endomorph of a unital algebra \( {\mathcal{A}} \) and the automorphism group of the simple right-symmetric algebra \( E(V_{n}) \)\( ( \)the endomorph of a direct sum of fields\( ) \).
