Spectral geometry of Kaehler submanifolds of a complex projective space By Seiichi UDAGAWA (Received June 29, 1984) (Revised Dec. 22, 1984)

\S 0. Introduction. Let $X:Marrow E^{N}$ be an isometric immersion of a compact Riemannian manifold into an N-dimensional Euclidean space. Then $X$ can be decomposed as $X$ , where is the k-th eigenfunction of the Laplacian of $M$ (for details, (resp. and see \S 2). We say that the immersion is of order if $X=X_{0}+X_{k_{1}}+X_{k_{2}}+X_{k_{3}}$ (resp. $X=X_{0}+X_{k_{1}}+X_{k_{2}}$ and $X=X_{0}+X_{k_{1}}$ ), where and $0
