Outline of Final Research Achievements

(1) For a complex or real hypersurface S in the 2-dimensional complex projective space P_2, we gave explicit formulas of the Levi form of the distance function d to S decided by Funini-Study metric. As its application, we also give the relations the constant 'a' with the function -(d to the a-th power) to be strictly plurisubharmonic and the curvature of S. In particular, we cannot choose the constant a=1/2.
(2) For a real hypersurface in the n-dimensional complex Euclidean space C_n, we give a new explicit formula of the Levi form of the distance function to S.
