On quasi-Albanese maps
Osamu Fujino
We discuss Iitaka's theory of quasi-Albanese maps in details. We also give a detailed proof of Kawamata's theorem on the quasi-Albanese maps for varieties of the logarithmic Kodair…
Log canonical inversion of adjunction
Osamu Fujino
This is a short note on the log canonical inversion of adjunction.
On vanishing theorems for analytic spaces
Osamu Fujino
This is a short report on our new vanishing theorems for projective morphisms between complex analytic spaces. We established a complex analytic generalization of Kollár's torsion-…
Positivity of extensions of vector bundles
Sho Ejiri, Osamu Fujino, Masataka Iwai
In this paper, we study when positivity conditions of vector bundles are preserved by extension. We prove that an extension of a big (resp. pseudo-effective) line bundle by an ampl…
Variation of mixed Hodge structure and its applications
Osamu Fujino, Taro Fujisawa
We discuss variations of mixed Hodge structure arising from projective morphisms of complex analytic spaces. Then we treat generalizations of Kollár's torsion-free theorem, vanishi…
On quasi-log structures for complex analytic spaces
Osamu Fujino
We introduce the notion of quasi-log complex analytic spaces and establish various fundamental properties. Moreover, we prove that a semi-log canonical pair naturally has a quasi-l…
