An Intial-Value Technique for Self-Adjoint Singularly Perturbed Two-Point Boundary Value Problems

open access: yesInternational Journal of Applied Mechanics and Engineering, 2020
In this paper, we present an initial value technique for solving self-adjoint singularly perturbed linear boundary value problems. The original problem is reduced to its normal form and the reduced problem is converted to first order initial value ...

The initial-boundary value problem for the biharmonic Schrödinger equation on the half-line [PDF]

open access: yesCommunications on Pure and Applied Analysis, 2018
We study the local and global wellposedness of the initial-boundary value problem for the biharmonic Schr\"odinger equation on the half-line with inhomogeneous Dirichlet-Neumann boundary data. First, we obtain a representation formula for the solution of

An initial-boundary value problem for the integrable spin-1 Gross-Pitaevskii equations with a 4 × 4 Lax pair on the half-line. [PDF]

open access: yesChaos, 2017
We extend the idea of the Fokas unified transform to investigate the initial-boundary value problem for the integrable spin-1 Gross-Pitaevskii equations with a 4 × 4 Lax pair on the half-line.

An initial boundary value problem for the Boussinesq equation in a Trapezoid [PDF]

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2022
This paper considers an initial boundary value problem for a one-dimensional Boussinesq-type equation in a domain, that is, a trapezoid. Using the methods of the theory of monotone operators, we establish theorems on their unique weak solvability in ...

Global Unique Solvability of the Initial-Boundary Value Problem for the Equations of One-Dimensional Polytropic Flows of Viscous Compressible Multifluids [PDF]

open access: yesJournal of Mathematical Fluid Mechanics, 2018
We consider the equations which describe polytropic one-dimensional flows of viscous compressible multifluids. We prove global existence and uniqueness of a solution to the initial-boundary value problem which corresponds to the flow in a bounded space ...
