摘要
本文讨论的积-微分算子是以众多应用领域为背景的无界的非自伴线性算子。运用L^2空间上的线性算子理论,我们证明了这类算子的占优本征值的存在性。
The integro-differential operators investigated in this paper are a class of unbounded non-selfadjoint operators arising form the various areas they are applied to. By using linear operator theory in L2 space, we proved the existence of dominant eigenvalues of the operators of this kind.
