Derived category of moduli of pointed curves -- II

Algebraic Geometry 2023-12-21 v4

Abstract

We show that the moduli space of stable rational curves with nn marked points has a full exceptional collection equivariant under the action of the symmetric group SnS_n permuting the marked points. In particular, its K-group with integer coefficients is a permutation SnS_n-lattice.
