A note on Tsuji's criterion for numerical triviality
Shigetaka Fukuda
In this study, we give an alternative and elementary proof to Tsuji's criterion for a Cartier divisor to be numerically trivial.
Note on the semiampleness theorem for the log canonical divisors on klt varieties which are nef and abundant
Shigetaka Fukuda
We give another alternative proof to the Kawamata semiampleness theorem for the log canonical divisors on klt varieties which are nef and abundant. After the first version of this…
An elementary semi-ampleness result for log canonical divisors
Shigetaka Fukuda
If the log canonical divisor on a projective variety with only Kawamata log terminal singularities is numerically equivalent to some semi-ample -divisor, then it is sem…
Note on quasi-numerically positive log canonical divisors
Shigetaka Fukuda
We propose a subconjecture that implies the semiampleness conjecture for quasi-numerically positive log canonical divisors and prove the semiampleness in some elementary cases.
Algebraic fiber space whose generic fiber and base space are of almost general type
Shigetaka Fukuda
We assume that the existence and termination conjecture for flips holds. A complex projective manifold is said to be {\it of almost general type} if the intersection number of the…
A note on the projective varieties of almost general type
Shigetaka Fukuda
A -Cartier divisor on a projective variety is {\it almost nup}, if for every very general curve on . An algebraic variety is of {\it al…
