On a semilinear elliptic equation with inverse-square potential [PDF]

open access: yesSelecta Mathematica, 2005
We study the existence and nonexistence of solutions to a semilinear elliptic equation with inverse-square potential. The dividing line with respect to existence or nonexistence is given by a critical exponent, which depends on the strength of the potential.

A Deep Neural Network Algorithm for Semilinear Elliptic PDEs with Applications in Insurance Mathematics

open access: yesRisks, 2020
In insurance mathematics, optimal control problems over an infinite time horizon arise when computing risk measures. An example of such a risk measure is the expected discounted future dividend payments.

Semilinear elliptic equations with Hardy potential and gradient nonlinearity [PDF]

open access: yesRevista matemática iberoamericana, 2019
Let $\Omega \subset {\mathbb R}^N$ ($N \geq 3$) be a $C^2$ bounded domain and $\delta$ be the distance to $\partial \Omega$. We study positive solutions of equation (E) $-L_\mu u+ g(|\nabla u|) = 0$ in $\Omega$ where $L_\mu=\Delta + \frac{\mu}{\delta^2} $

Isolated boundary singularities of semilinear elliptic equations [PDF]

open access: yesCalculus of Variations and Partial Differential Equations, 2010
Given a smooth domain $ \subset\RR^N$ such that $0 \in \partial $ and given a nonnegative smooth function $ $ on $\partial $, we study the behavior near 0 of positive solutions of $- u=u^q$ in $ $ such that $u = $ on $\partial \setminus\{0\}$. We prove that if $\frac{N+1}{N-1} < q < \frac{N+2}{N-2}$, then $u(x)\leq C \abs{x}^{-\frac{2}{q-

Analysis of Optimal Control Problems of Semilinear Elliptic Equations by BV-Functions [PDF]

open access: yesSet-Valued and Variational Analysis, 2017
Optimal control problems for semilinear elliptic equations with control costs in the space of bounded variations are analysed. BV-based optimal controls favor piecewise constant, and hence ’simple’ controls, with few jumps. Existence of optimal controls,

A multiscale method for semilinear elliptic equations

open access: yesJournal of Mathematical Analysis and Applications, 2008
AbstractAt present there are many papers, based on multiscale expansion and homogenization theory, to deal with nonlinear problems with microstructure. But there is no systematic method to deal with all of the possible nonlinear partial differential equations since different nonlinear problems gives rise to different multiscale expansions parameters ...

On a class of semilinear elliptic problems near critical growth

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1998
We use Minimax Methods and explore compact embedddings in the context of Orlicz and Orlicz-Sobolev spaces to get existence of weak solutions on a class of semilinear elliptic equations with nonlinearities near critical growth. We consider both biharmonic

On an inverse problem for a fractional semilinear elliptic equation involving a magnetic potential [PDF]

open access: yesJournal of Differential Equations 296(2021) 170-185, 2020
We study a class of fractional semilinear elliptic equations and formulate the corresponding Calder\'on problem. We determine the nonlinearity from the exterior partial measurements of the Dirichlet-to-Neumann map by using first order linearization and the Runge approximation property.
