Résumé: 

A question of Orlov is whether the derived category of the Grothendieck--Knudsen moduli space of stable, rational curves with n markings admits a full, strong, exceptional collection that is invariant under the action of the symmetric group S_n. I will present an approach towards answering this question. This is joint work with Jenia Tevelev.
