On $ G$-Fano threefolds

On $ G$-Fano threefolds

We study Fano threefolds with terminal singularities admitting a "minimal" action of a finite group.We prove that under certain additional assumptions such a variety does not contain planes.We also obtain an upper bounds of the number of singular points of certain Fano threefolds with terminal factorial singularities.1 2 (-K X …
