Abstract:
In this talk I will tell about a classification of rational $G$-del Pezzo
threefolds which have no birational maps
to more simple $G$-varieties and have no structures of $G$-Mori fibration with
the base of positive dimension.
Such varieties give us new finite subgroups in the Cremona group of rank $3$.
