| Research Abstract |
We investigated shape of 4-dimensional spaces using partial differential equations which were related to physics.
(1) Formulation of a Pontrjagin-Thom construction to describe the stable homotopy version of the Seiberg-Witten invariant(joint with Tian-Jun Li).
(2) Construction of a local coefficient version of the Seiberg-Witten monopole equation. As an application Nobuhiro Nakamura obtained a restriction on the intersection form of 4-dimensional smooth manifolds with local coefficients.
(3) Clarification and generalization for the mechanism of the localization of the index of Dirac operators on symplectic manifolds to Bohr-Sommerfeld orbits(joint with Takahiko Yoshida and Hajime Fujita.)
