Research Abstract |
Though a generalization of Do Carmo-Wallach theory on moduli spaces of minimal immersions between spheres was achieved by me, I succeeded to refine it. To do so, I define a new equivalence relation of maps called gauge equivalence of maps. This gives a unified proof of results which were obtained in another ways. In addition, I described a moduli spaces of holomorphic isometric embeddings of complex projective lines into complex quadrics. Moreover, I defined a projectively flat immersions into complex Grassmannian and obtained some properties of projectively flat immersions. On the other hand, I got principal curvatures of isoparametric hypersurfaces of compact symmetric spaces. Such hypersurfaces was defined by isoparametric functions induced from sections of vector bundles. Invariants of submanifolds are related to invariants of connections on vector bundles.
