Abstract

Abstract We give a classification of Fano threefolds X with canonical Gorenstein singularities such that X possess a regular involution which acts freely on some smooth surface in |– KX |, and such that the linear system |– KX | gives a morphism which is not an embedding. From this classification one gets, in particular, a description of some natural class of Fano–Enriques threefolds.
