A Priori and a Posteriori Error Analysis for Generic Linear Elliptic Problems

open access: yesTikrit Journal of Pure Science, 2022
In this paper, a priori error analysis has been examined for the continuous Galerkin finite element method which is used for solving a generic scalar and a generic system of linear elliptic equations.

Analytic theory of difference equations with rational and elliptic coefficients and the Riemann-Hilbert problem

open access: yes, 2004
A new approach to the analytic theory of difference equations with rational and elliptic coefficients is proposed. It is based on the construction of canonical meromorphic solutions which are analytical along "thick paths".

On singular elliptic equations with measure sources [PDF]

open access: yes, 2015
We prove existence of solutions for a class of singular elliptic problems with a general measure as source term whose model is \begin{eqnarray} \begin{cases} \dys -\Delta u = \frac{f(x)}{u^{\gamma}} +\mu & \text{in}\ \Omega,\\[2mm] u=0 &\text{on ...

Elliptic solutions to difference non-linear equations and related many-body problems

open access: yes, 1997
We study algebro-geometric (finite-gap) and elliptic solutions of fully discretized KP or 2D Toda equations. In bilinear form they are Hirota's difference equation for $\tau$-functions.

Hölder Regularity of Solutions to Second-Order Elliptic Equations in Nonsmooth Domains

open access: yesBoundary Value Problems, 2006
We establish the global Hölder estimates for solutions to second-order elliptic equations, which vanish on the boundary, while the right-hand side is allowed to be unbounded.

New non-linear equations and modular form expansion for double-elliptic Seiberg-Witten prepotential

open access: yes, 2016
Integrable N-particle systems have an important property that the associated Seiberg-Witten prepotentials satisfy the WDVV equations. However, this does not apply to the most interesting class of elliptic and double-elliptic systems.

Elliptic Dunkl operators, root systems, and functional equations [PDF]

open access: yes, 1994
We consider generalizations of Dunkl's differential-difference operators associated with groups generated by reflections. The commutativity condition is equivalent to certain functional equations. These equations are solved in many cases.

On oscillatory elliptic equations on manifolds [PDF]

open access: yesTransactions of the American Mathematical Society, 1980
In this note we investigate the possibility of oscillatory behavior for a second-order selfadjoint elliptic operators on noncompact Riemannian manifolds (M, g). Let A be such an operator which is semibounded below and symmetric on C 0 ∞ ( M ) ⊆

Einstein equations under polarized $\mathbb U(1)$ symmetry in an elliptic gauge

open access: yes, 2017
We prove local existence of solutions to the Einstein--null dust system under polarized $\mathbb U(1)$ symmetry in an elliptic gauge. Using in particular the previous work of the first author on the constraint equations, we show that one can identify ...
