| Research Abstract |
The Futaki invariant is an obstruction to the existence of Kahler-Einstein metrics. In this research we give an relation between the Futaki invariant and the Witten's holonomy of a fiber bundle with fiber F and base space B where F is a compact complex manifold and B is the circle. This result is published in
K.Tsuboi, On the Einstein-Kahler metric and the holonomy of a line bundle, Proc.Edinburgh Math.Soc., Vol.45(2002), 83-90.
The sphere of zero or one or three dimension have a group structure. In this research using this structure we give a new formula for the fixed point data of finite group action on compact almost complex manifolds. This result is published in
K.Tsuboi, A fixed point formula for compact complex manifolds, J.Math.Kyoto Univ., Vol. 42 (2002), 1-20.
Group action on manifolds represents the symmetry of manifolds. In this research we made a discovery of a new method to use the equivariant determinant of elliptic operators as an obstruction to the existence of finite group actions on compact manifolds. This result is published in
K.Tsuboi, The finite group action and the equivariant determinant of elliptic operators, J.Math.Soc.Japan, vol.57 (2005), 95-113.
