Title: G-birationally rigid cubic threefolds

Abstract: A Fano variety X equipped with an action of a group G is called G-birationally rigid if X is a G-Mori fibred space (over a point) and X is not G-birational to any other G-Mori fibre space. In this talk I will classify all pairs (X,G) consisting of a (possibly singular) cubic threefold X and a subgroup G of its automorphism group such that X is G-birationally rigid.
