Liouville\u27s theorems for Lévy operators

Let $L$ be a Lévy operator. A function $h$ is said to be harmonic with respect to $L$ if $L h = 0$ in an appropriate sense. We prove Liouville\u27s theorem for positive functions harmonic with respect to a general Lévy operator $L$: such functions are ...

Liouville theorems for conformally invariant fully nonlinear equations. I

A fundamental theorem of Liouville asserts that positive entire harmonic functions in Euclidean spaces must be constant. A remarkable Liouville-type theorem of Caffarelli-Gidas-Spruck states that positive entire solutions of $-Δu=u^{ {(n+2)}/{(n-2)} }$, $
