Elliptic Hypergeometric Solutions to Elliptic Difference Equations [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2009
It is shown how to define difference equations on particular lattices {x_n}, n in Z, made of values of an elliptic function at a sequence of arguments in arithmetic progression (elliptic lattice). Solutions to special difference equations have remarkable

The Existence of Entropy Solutions for an Elliptic Problems Involving Variable Exponent

open access: yesJournal of Harbin University of Science and Technology, 2022
In order to study the entropy solution of a class of quasilinear elliptic equations with variable exponents, first, the approximation problem of elliptic equations is established under weak operator conditions, and then the Sobolev embedding theorem ...

EQUIVALENCE OF THE FREDHOLM SOLVABILITY CONDITION FOR THE NEUMANN PROBLEM TO THE COMPLEMENTARITY CONDITION

open access: yesВестник КазНУ. Серия математика, механика, информатика, 2021
The methods of complex analysis constitute the classical direction in the study of elliptic equations and mixed-type equations on the plane and fundamental results have now been obtained. In the early 60s of the last century, a new theoretical-functional

A remark on partial data inverse problems for semilinear elliptic equations [PDF]

open access: yesProceedings of the American Mathematical Society, 2019
We show that the knowledge of the Dirichlet-to-Neumann map on an arbitrary open portion of the boundary of a domain in $\mathbb{R}^n$, $n\ge 2$, for a class of semilinear elliptic equations, determines the nonlinearity uniquely.

Elliptic blowup equations for 6d SCFTs. Part IV. Matters

open access: yesJournal of High Energy Physics, 2021
Given the recent geometrical classification of 6d (1, 0) SCFTs, a major question is how to compute for this large class their elliptic genera. The latter encode the refined BPS spectrum of the SCFTs, which determines geometric invariants of the ...

Differential-Difference Elliptic Equations with Nonlocal Potentials in Half-Spaces

open access: yesMathematics, 2023
We investigate the half-space Dirichlet problem with summable boundary-value functions for an elliptic equation with an arbitrary amount of potentials undergoing translations in arbitrary directions.

Multiplicity results for $(p,q)$ fractional elliptic equations involving critical nonlinearities [PDF]

open access: yesAdvances in Differential Equations, 2018
In this paper we prove the existence of infinitely many nontrivial solutions for the class of $(p,\, q)$ fractional elliptic equations involving concave-critical nonlinearities in bounded domains in $\mathbb{R}^N$.

Regularity for Fully Nonlinear Elliptic Equations with Oblique Boundary Conditions [PDF]

open access: yesArchive for Rational Mechanics and Analysis, 2017
In this paper, we obtain a series of regularity results for viscosity solutions of fully nonlinear elliptic equations with oblique derivative boundary conditions. In particular, we derive the pointwise Cα, C1,α and C2,α regularity. As byproducts, we also

open access: yesProceedings of the American Mathematical Society, 1983
In this paper, we study the singular elliptic equation L u + K ( x ) u p = 0 Lu + K(x){u^p} = 0 , where L L is a uniformly elliptic operator of divergence form, p > 1 ...
