Elliptic equations and Gaussian processes [PDF]

open access: yesJournal of Functional Analysis, 1980
AbstractWe consider a Gaussian process P on s(Rd) generated by a polynomial in the Laplace operator. We prove some support properties for P. As a byproduct we strenghten earlier results on the stochastic Dirichlet problem on bounded regions Λ ⊂ Rd. We describe in this way the conditional P-distribution of the restriction to Λ of s(Rd), supposing ϑ is ...

Elliptic Gaudin models and elliptic KZ equations [PDF]

open access: yesNuclear Physics B, 2002
The Gaudin models based on the face-type elliptic quantum groups and the $XYZ$ Gaudin models are studied. The Gaudin model Hamiltonians are constructed and are diagonalized by using the algebraic Bethe ansatz method. The corresponding face-type Knizhnik-Zamolodchikov equations and their solutions are given.

A primal-dual weak Galerkin finite element method for second order elliptic equations in non-divergence form [PDF]

open access: yesMathematics of Computation, 2015
This article proposes a new numerical algorithm for second order elliptic equations in non-divergence form. The new method is based on a discrete weak Hessian operator locally constructed by following the weak Galerkin strategy. The numerical solution is

Cotton-Type and Joint Invariants for Linear Elliptic Systems

open access: yesThe Scientific World Journal, 2013
Cotton-type invariants for a subclass of a system of two linear elliptic equations, obtainable from a complex base linear elliptic equation, are derived both by spliting of the corresponding complex Cotton invariants of the base complex equation and from

Critical Sets of Elliptic Equations [PDF]

open access: yesCommunications on Pure and Applied Mathematics, 2014
Given a solution u to a linear, homogeneous, second‐order elliptic equation with Lipschitz coefficients, we introduce techniques for giving improved estimates of the critical set 𝒷(u)u {x :|δu|(x) = 0}, as well as the first estimates on the effective critical set 𝒷r(u), which roughly consists of points x such that the gradient of u is small somewhere ...

On a Singular Elliptic Equation [PDF]

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 ...

Elliptic scattering equations [PDF]

open access: yesJournal of High Energy Physics, 2016
في الآونة الأخيرة، تم توسيع نهج CHY إلى مستوى حلقة واحدة باستخدام الوظائف الإهليلجية والأشكال المعيارية على صنف جاكوبي. نظرًا لصعوبة التلاعب بهذا النوع من الوظائف، نقترح وصفة طبية بديلة جبرية تمامًا. يعتمد هذا الاقتراح الجديد على منحنى جبري إهليلجي مضمن في مساحة $\mathbb{C}P^2 $.

Existence of positive weak solutions for a class of singular elliptic equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2011
In this note, we are concerned with positive solutions for a class of singular elliptic equations. Under some conditions, we obtain weak solutions for the equations by elliptic regularization method and sub-super solution method.
