| Research Abstract |
１． We characterize an affine immersion from a manifold with almost product structure or an almost complex structure to a real affine space whose affine fundamental form is Hermitian or anti-Hermitian with the structure. As an application, we study an isometric immersion of a para-Kaehler manifold or an almost product Riemannian manifold, which is a manifold with metric which is compatible with the structures. Especially, we classify a para-pluriharmonic isometric immersion from a complete para-Kaehler manifold of codimension one or two.
２． We find a new construction of a tt*-bundle structure associated with a harmonic map from a Riemann surface into a sphere, that is a collaboration work with Katsuhiro Moriya. This construction is related to the Clifford algebra.
