Spectral Analysis of Discontinuous Boundary-Value Problems with Retarded Argument
(B Verkin Inst Low Temperature Physics & Engineering, 2018)In the paper, we are concerned with spectral properties of discontinuous Sturm-Liouville type problems with retarded argument. We extend and generalize some approaches and results of the classical regular and discontinuous ... -
Solvability of A Nonlocal Problem By A Novel Concept of Fundamental Function
(Georgian Natl Acad Sciences, 2018)Cauchy function, Green function and Riemann function are the several of the fundamental functions used frequently in the expression of a fundamental solution in the literature. In order to construct such functions, various ... -
Invariant subspaces of operators quasi-similar to L-weakly and M-weakly compact operators

On solutions of the fifth-order dispersive equations with porous medium type non-linearity
(Taylor & Francis Ltd, 2018)In this work, we focus on obtaining the exact solutions of the fifth-order semi-linear and non-linear dispersive partial differential equations, which have the second-order diffusion-like (porous-type) non-linearity. The ... -
Determining the optimal parameters for the MHD flow and heat transfer with variable viscosity and Hall effect
(Pergamon-Elsevier Science Ltd, 2018)The direct and optimal control solution of the laminar, fully developed, steady MHD flow of an incompressible, electrically conducting fluid in a duct is considered together with the heat transfer. The flow is driven by a ... -
