Semilinear elliptic equations with singular nonlinearities

Calculus of Variations and Partial Differential Equations, 2009
We prove existence, regularity and nonexistence results for problems whose model is $$-\Delta u = \frac{f(x)}{u^{\gamma}}\quad {{\rm in}\,\Omega},$$ with zero Dirichlet conditions on the boundary of an open, bounded subset Ω of \({\mathbb{R}^{N}}\). Here γ > 0 and f is a nonnegative function on Ω.

G-convergence and semilinear elliptic equations

Asymptotic Analysis, 1991
We study the behavior of positive solutions of semilinear elliptic equations −div(aε(x)Duε=g(uε) with homogeneous Dirichlet boundary data, with respect to the G-convergence of the elliptic matrices aε. Here the function g has a subcritical or critical growth with respect to Sobolev imbedding.

Semilinear elliptic equations with additive noise

2017
With temporal white noise, the solutions of stochastic parabolic equations have low regularity in time (Holder continuous with exponent 1∕2 −e and e > 0 is arbitrarily small) and thus the spectral approximation of Brownian motion leads to only half order convergence in its truncation mode n.
