In Kantor and Trishin (1997) , Kantor and Trishin described the algebra of polynomial invariants of the adjoint representation of the Lie superalgebra gl(m|n) and a related algebra As of what they called pseudosymmetric polynomials over an algebraically closed field K of characteristic zero. The algebra As was investigated earlier by Stembridge (1985) who in  called the elements of As supersymmetric polynomials and determined generators of As.The case of positive characteristic p of the ground field K has been recently investigated by La Scala and Zubkov (in press) in . We extend their work and give a complete description of generators of polynomial invariants of the adjoint action of the general linear supergroup GL(m|n) and generators of As.
