Nonexistence of solutions to KPP-type equations of dimension greater than or equal to one

Electronic Journal of Differential Equations, 2006
In this article, we consider a semilinear elliptic equations of the form $Delta u+f(u)=0$, where $f$ is a concave function. We prove for arbitrary dimensions that there is no solution bounded in $(0,1)$.

Harnack inequality for non-divergence structure semi-linear elliptic equations

Advances in Nonlinear Analysis, 2018
In this paper we establish a Harnack inequality for non-negative solutions of L⁢u=f⁢(u){Lu=f(u)} where L is a non-divergence structure uniformly elliptic operator and f is a non-decreasing function that satisfies an appropriate growth conditions at ...

Dimension of the set of positive solutions to nonlinear equations and applications

Electronic Journal of Differential Equations, 2016
We study the covering dimension of the set of (positive) solutions to various classes of nonlinear equations involving condensing and A-proper maps. It is based on the nontriviality of the fixed point index of a certain condensing map or on oddness ...
