On classification of finite dimensional algebras

Rings and Algebras 2015-09-24 v3

Abstract

Classification and invariants, with respect to basis changes, of finite dimensional algebras are considered. An invariant open, dense (in the Zariscki topology) subset of the space of structural constants is defined. The algebras with structural constants from this set are classified and a basis to the field of invariant rational functions of structural constants is provided.

Comments

The main changes are due to the drop of the statement on rationality of the extension $F\subset F(x)^{GL(m,F)}$ from Theorem 2.2 because lack of justification. In section 2 instead of $GL(m,F)$ any algebraic subgroup $G$ of it is considered
