Based on theorm about the S-hermitian boundary-value problems of Albert Schneider,the theory of selfadjoint subspaces and regular S-hermite eigenvalue problems,by add conditions,a conclusion is obtained:If is S-hermitian,normal,reducible and have the Fredholm property,then is of finite defect.
在基于Albert Schneider的S-hermite边值问题、自伴子空间理论和正则S-hermite特征值问题现有定理的基础上,通过附加条件后,得出若为S-hermite的、正规的、可约的且具有Fredholm性质,则为有限亏量。
