General heart construction on a triangulated category (II): Associated cohomological functor
Noriyuki Abe, Hiroyuki Nakaoka
In the preceding part (I) of this paper, we showed that for any torsion pair (i.e., -structure without the shift-closedness) in a triangulated category, there is an associated a…

Cohomology theory in 2-categories
Hiroyuki Nakaoka
Recently, symmetric categorical groups are used for the study of the Brauer groups of symmetric monoidal categories. As a part of these efforts, some algebraic structures of the 2-…

Mackey-functor structure on the Brauer groups of a finite Galois covering of schemes
Hiroyuki Nakaoka
Past studies of the Brauer group of a scheme tells us the importance of the interrelationship among Brauer groups of its finite étale coverings. In this paper, we consider these gr…
