Abstract
We prove that the pull-back of a quasi-log scheme by a smooth quasi-projective morphism has a natural quasi-log structure. We treat an application to log Fano pairs. This paper also contains a proof by Kento Fujita of the simple connectedness of log Fano pairs with only log canonical singularities.
