Abstract:
A result confirming the Regev conjecture for the codimension of associative algebras with unit which are of PI-exponent 2 is obtained. It is proved that the sequence of multiplicities of irreducible summands in proper cocharacters of algebras of PI-exponent 2 is of period 2, beginning with some index, whereas this sequence is constant for the ordinary cocharacters of the algebras of PI-exponent 1.
Keywords:
associative algebra, free associative algebra, PI-exponent, algebra of PI-exponent 2, irreducible cocharacter, Young tableau, algebra of polynomial growth.
