Representation stability for the Kontsevich space of stable maps

Algebraic Geometry 2022-07-07 v2 Algebraic Topology

Abstract

For a fixed algebraic variety XX, curve class αN1(X)\alpha \in N_1(X), and genus gNg \in \mathbb N, we consider the sequence of SnS_n representations obtained from the homology of the Kontsevich space of stable maps to XX, Mˉg,n(X,α)\bar M_{g,n}(X,\alpha). Using the category of finite sets and surjections, we prove a representation stability theorem that governs the behavior of this sequence of representations for nn sufficiently large.
