Resolvent for Non-Self-Adjoint Differential Operator with Block-Triangular Operator Potential
Abstract and Applied Analysis, 2016 A resolvent for a non-self-adjoint differential operator with a block-triangular operator potential, increasing at infinity, is constructed. Sufficient conditions under which the spectrum is real and discrete are obtained.

Calculation of Eigenvalues of Discrete Semibounded Differential Operators
Journal of Computational and Engineering Mathematics, 2017 Summary: We consider a problem of eigenvalues of an abstract discrete semibounded operator acting in a separable Hilbert space. The existence and uniqueness of the solution, as well as a convergence of the Galerkin method with reference to the problem, are proved. Simple formulas to calculate the eigenvalues are obtained. The formulas based on Galerkin

Finite eigenfuction approximations for continuous spectrum operators
International Journal of Mathematics and Mathematical Sciences, 1993 In this paper, we introduce a new formulation of the theory of continuous spectrum eigenfunction expansions for self-adjoint operators and analyze the question of when operators may be approximated in an operator norm by finite sums of multiples of ...

𝑘-discrete differentials of certain operators on Banach spaces [PDF]
Proceedings of the American Mathematical Society, 1981 By observing a convex property of discrete differences, one-sided k k -discrete, k k -discrete Gâteaux and k k -discrete Fréchet differentials are introduced. It is proved that a locally bounded n n -convex function has k k -discrete Fréchet differentials for
