Abstract:
In this talk we will classify threedimensional $G$del Pezzo varieties of degree $3$ and $4$ which can be $G$birationally rigid. For some of them we will prove their $G$birational rigidity. Also we will prove an analogue of the theorem of Sarkisov about existence of a standard model in the case of conic $G$fibrations.
