Abstract: Let $\gamma$ be an automorphism of a polarized complex projective manifold$M,L$. Then $\gamma$ induces an automorphism $\gamma k$ of the space ofglobal holomorphic sections of the $k$-th tensor power of $L$, for every$k=1,2, .$; for $k\gg 0$, the Lefschetz fixed point formula expresses thetrace of $\gamma k$ in terms of fixed point data. More generally, one mayconsider the composition of $\gamma k$ with the Toeplitz operator associated tosome smooth function on $M$. Still more generally, in the presence of thecompatible action of a compact and connected Lie group preserving$M,L,\gamma$, one may consider induced linear maps on the equivariantsummands associated to the irreducible representations of $G$. In this paper,under familiar assumptions in the theory of symplectic reductions, we show thatthe traces of these maps admit an asymptotic expansion as $k\to +\infty$, andcompute its leading term.
