Splitting criterion for reflexive sheaves
Takuro Abe, Masahiko Yoshinaga
The purpose of this paper is to study the structure of reflexive sheaves over projective spaces through hyperplane sections. We give a criterion for a reflexive sheaf to split into…

Some characterizations of freeness of hyperplane arrangement
Masahiko Yoshinaga
We will consider some characterizations of freeness of a hyperplane arrangement, in terms of the following properties: locally freeness, factorization of characteristic polynomial…

The primitive derivation and freeness of multi-Coxeter arrangements
Masahiko Yoshinaga
We will prove the freeness of multi-Coxeter arrangements by constructing a basis of the module of vector fields which contact to each reflecting hyperplanes with some multiplicitie…
