Minimal model theory for relatively trivial log canonical pairs
We study relative log canonical pairs with relatively trivial log canonical
divisors. We fix such a pair and establish the minimal model
theory for the pair assuming the minimal model theory for all
Kawamata log terminal pairs whose dimension is not greater than .
We also show the finite generation of log canonical rings for log canonical
pairs of dimension five which are not of log general type.Comment: 38 pages, final version. The statement of Theorem 1.2 was replaced by
that of Theorem 4.2, which was equivalent to Theorem 1.2. Accompanied by
this, Lemma 4.1 and Theorem 4.2 was removed. Numbering of definitions and
others in Section 2 and Section 4 was changed. Other minor changes. To appear

ADJUNCTION AND INVERSION OF ADJUNCTION
We establish adjunction and inversion of adjunction for log canonical centers of arbitrary codimension in full generality
