Research Field :
Moduli space of vector bundles on algebraic surfaces

Research Summary :
I study moduli space of vector bundles on algebraic surfaces,
especially the projective plane. Recently, I am investigating the
functional equation of the Nekrasov function using wall-crossing
formula by Takuro Mochizuki.
