| Outline of Final Research Achievements |
We have mainly investigated and developed the Pin(2)-monopole theory for applications to 4-dimensional topology and geometry. The results of this study are as follows: 1.Computations and applications of the Pin(2)-monopole invariants. In particular, the connected-sum formula, applications to exotic structures and computations of Yamabe invariants. 2.Formulation and computations of stable cohomotopy invariants. 3.Pin(2)-moopole theory on 4-manifolds with boundary and applications to intersection forms with local coefficients. 4.Nonvanishing theorem for almost Kaehler surfaces with real structures.
