Abstract

Let FYZ,F\langle Y \cup Z, \ast \rangle be the free \ast-superalgebra over a field FF of characteristic zero and let ΓM±,L± \Gamma^\ast_{M^{\pm}, L^{\pm}} be the TZ2T^\ast_{\mathbb{Z}_2}-ideal generated by the set of the \ast-graded Capelli polynomials CapM+(Z2,)[Y+,X]Cap^{(\mathbb{Z}_2, \ast)}_{M^+} [Y^+,X], CapM(Z2,)[Y,X]Cap^{(\mathbb{Z}_2, \ast)}_{M^-} [Y^-,X], CapL+(Z2,)[Z+,X]Cap^{(\mathbb{Z}_2, \ast)}_{L^+} [Z^+,X], CapL(Z2,)[Z,X]Cap^{(\mathbb{Z}_2, \ast)}_{L^-} [Z^-,X] alternating on M+M^+ symmetric variables of homogeneous degree zero, on MM^- skew variables of homogeneous degree zero, on L+L^+ symmetric variables of homogeneous degree one and on LL^- skew variables of homogeneous degree one, respectively. We study the asymptotic behavior of the sequence of \ast-graded codimensions of ΓM±,L±.\Gamma^\ast_{M^{\pm}, L^{\pm}}. In particular we prove that the \ast-graded codimensions of the finite dimensional simple \ast-superalgebras are asymptotically equal to the \ast-graded codimensions of ΓM±,L±\Gamma^\ast_{M^{\pm}, L^{\pm}}, for some fixed natural numbers M+,M,L+M^+, M^-, L^+ and LL^-.
