Algebras with bounded multiplicities of the central cocharacters

Wesley Q. Cota, Luiz H. S. Matos, Breno O. Souza

Let $A$ be an associative PI-algebra over a field of characteristic zero. The central polynomials of $A$ give rise to a sequence $\{{\chi }_n^z(A){\}}_{n\ge 1}$ of $S_n$-characters, calle…
