Abstract

Consider a log canonical pair (X,B)(X,B) such that there is a Cartier divisor DD for which TX(logB)O(D)T_X(-\log B) \otimes \mathcal O(D) is locally free and globally generated. Let F\mathcal F be a log canonical foliation of rank 1 on XX. We prove that there exists a divisor Γ\Gamma such that (X,Γ)(X, \Gamma) is log canonical and KX+ΓKF+DK_X + \Gamma \sim K_{\mathcal F} + D. We then apply this result to prove several statements on the birational geometry of rank 1 log canonical foliations on log homogeneous varieties.
