On birational involutions of P³
Prokhorov, Yuri
Original · EN
Let X be a rationally connected three-dimensional algebraic variety and let τ be an element of order two in the group of its birational selfmaps. Suppose that there exists a non-uniruled divisorial component of the τ-fixed point locus. Using the equivariant minimal model program we give a rough classification of such elements.
