Investigation of Negative Critical Points of the Characteristic Function for Problems with Nonlocal Boundary Conditions

open access: yesNonlinear Analysis, 2008
In this paper the Sturm-Liouville problem with one classical and the other nonlocal two-point or integral boundary condition is investigated. Critical points of the characteristic function are analyzed.

An inverse boundary value problem for transverse vibrations of a bar

open access: yesBoundary Value Problems, 2022
In this article, we study an inverse problem (IP) for a fourth-order hyperbolic equation with nonlocal boundary conditions. This IP is reduced to the not self-adjoint boundary value problem (BVP) with corresponding boundary condition.

Finite to infinite steady state solutions, bifurcations of an integro-differential equation [PDF]

open access: yes, 2011
We consider a bistable integral equation which governs the stationary solutions of a convolution model of solid–solid phase transitions on a circle. We study the bifurcations of the set of the stationary solutions as the diffusion coefficient is varied to ...

On a Nonlocal Boundary Value Problem of a State-Dependent Differential Equation

open access: yesMathematics, 2021
In this paper, the existence of absolutely continuous solutions and some properties will be studied for a nonlocal boundary value problem of a state-dependent differential equation. The infinite-point boundary condition and the Riemann–Stieltjes integral

On a multipoint nonlocal initial value problem for a singularly-perturbed first-order ODE [PDF]

open access: yesE-Journal of Analysis and Applied Mathematics, 2019
A linear first order ordinary differential equation (ODE) with a positive parameter $\varepsilon$ and a multipoint nonlocal initial value condition (NLIVC) is considered.

Spectrum Curves for Sturm–Liouville Problem with Integral Boundary Condition

open access: yesMathematical Modelling and Analysis, 2015
We consider Sturm–Liouville problem with one integral type nonlocal boundary condition depending on three parameters γ (multiplier in nonlocal condition), ξ1, ξ2 ([ξ1, ξ2] is a domain of integration).

Application of Rothe's method to a parabolic inverse problem with nonlocal boundary condition [PDF]

open access: yes, 2022
summary:We consider an inverse problem for the determination of a purely time-dependent source in a semilinear parabolic equation with a nonlocal boundary condition. An approximation scheme for the solution together with the well-posedness of the problem

Polymeric Sorbents as Energy‐Efficient Alternative to Cryogenic Distillation for Light Hydrocarbon Purification

open access: yesAdvanced Materials, EarlyView.
The transition from cryogenic distillation to polymeric sorbents for light hydrocarbon purification is crucial for energy and environmental sustainability. The polymeric sorbents are engineered to separate gas mixtures based on their specific properties.
