Boundary conditions for integrable equations [PDF]

open access: yesJournal of Physics A: Mathematical and General, 1997
Summary: The problem of constructing boundary conditions for nonlinear equations compatible with higher symmetries is considered. In particular, this problem is discussed for the sine-Gordon, Jiber-Shabat, Liouville and KdV equations. New results are obtained for the last two ones.

Constant-Sign Green’s Function of a Second-Order Perturbed Periodic Problem

open access: yesAxioms, 2022
In this paper, we were interested in obtaining the exact expression and studying the regions of constant sign of Green’s function related to a second-order perturbed periodic problem coupled with integral boundary conditions at the extremes of the ...

Path Integral Solution of Linear Second Order Partial Differential Equations I. The General Construction [PDF]

open access: yes, 2004
A path integral is presented that solves a general class of linear second order partial differential equations with Dirichlet/Neumann boundary conditions. Elementary kernels are constructed for both Dirichlet and Neumann boundary conditions.

Integral boundary conditions in phase field models

open access: yesComputers & Mathematics with Applications, 2023
Modeling the chemical, electric, and thermal transport as well as phase transitions and the accompanying mesoscale microstructure evolution within a material in an electronic device setting involves the solution of partial differential equations often with integral boundary conditions.

On singular $p$-Laplacian boundary value problems involving integral boundary conditions

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2019
We prove the existence of positive solutions for the $p$-Laplacian equations \[-(\phi (u^{\prime }))^{\prime }=\lambda f(t,u),\qquad t\in (0,1) \] with integral boundary conditions. Here $\lambda $ is a positive parameter, $\phi (s)=|s|^{p-2}s,p>1,\ f:(0,

Boundaries of Graphs of Harmonic Functions [PDF]

open access: yes, 2009
Harmonic functions $u:{\mathbb R}^n \to {\mathbb R}^m$ are equivalent to integral manifolds of an exterior differential system with independence condition $(M,{\mathcal I},\omega)$.

Weber-Type Integral Transform Connected with Robin-Type Boundary Conditions

open access: yesMathematics, 2020
A new Weber-type integral transform and its inverse are defined for the representation of a function f(r,t), (r,t)∈[R,1]×[0,∞) that satisfies the Dirichlet and Robin-type boundary conditions f(R,t)=f1(t), f(1,t)−α∂f(r,t)∂r|r=1=f2(t), respectively.
