Outline of Final Research Achievements |
In order to discritize the index theorem, we first established the Ginsparg-Wilson index theorem, which appears when we deal with combinatorial or finite-dimensional operators. Second, we clarified the relation between the Callias index theorem and the Roe algebra for complete Riemannian manifolds. Third, we investigated the Bott-Virasoro class and the space of equicentro-affine curves on the plane and proved the existence of a momentum map for the symplectic action of the diffeomorphism group of unit circle.
