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.

Linear Sturm-Liouville problems with Riemann-Stieltjes integral boundary conditions [PDF]

open access: yesOpuscula Mathematica, 2018
We study second-order linear Sturm-Liouville problems involving general homogeneous linear Riemann-Stieltjes integral boundary conditions. Conditions are obtained for the existence of a sequence of positive eigenvalues with consecutive zero counts of the

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.

Integrable open boundary conditions for XXC models [PDF]

open access: yesJournal of High Energy Physics, 1998
The XXC models are multistate generalizations of the well known spin 1/2 XXZ model. These integrable models share a common underlying su(2) structure. We derive integrable open boundary conditions for the hierarchy of conserved quantities of the XXC models .

Distribution theory for Schr\"odinger's integral equation [PDF]

open access: yes, 2015
Much of the literature on point interactions in quantum mechanics has focused on the differential form of Schr\"odinger's equation. This paper, in contrast, investigates the integral form of Schr\"odinger's equation.
