In this thesis, we mainly study the relations between compact minimal hypersurfaces of S~(n+1)(1) and the Clifford minimal hypersurface of S~(n+1)(1) by their spectrums, and the relations between unit tangent sphere bundle T_1 M and its base manifold M.
在本文中,我们主要通过谱研究了S~(n+1)(1)中的紧致极小超曲面和S~(n+1)(1)中的Clifford极小超曲面之间的关系,以及单位切球丛T_1M与它的底流形M之间的关系。
The possible form of the total Stiefel-Whitney classes of vector bundles on RP(j)×CP(k) is determined in this paper.

By using some results on the existence of rank two special stable vector bundles over generic curves of genus 5, we give count-examples to show that both Maruyama s conjecture and Arrondo-Sols conjecture are false on generic curves of genus 5.
