Abstract

Star-fundamental algebras are special finite dimensional algebras with involution {*} over an algebraically closed field of characteristic zero defined in terms of multialternating {*}-polynomials. We prove that the upper-block matrix algebras with involution introduced in Di Vincenzo and La Scala {[}J. Algebra 317 (2007), pp. 642-657] are star-fundamental. Moreover, any finite dimensional algebra with involution contains a subalgebra mapping homomorphically onto one of such algebras. We also give a characterization of star-fundamental algebras through the representation theory of the symmetric group. (AU)
