Liouville theorems and universal estimates for superlinear parabolic problems without scale invariance

We establish Liouville type theorems in the whole space and in a half-space for parabolic problems without scale invariance. To this end, we employ two methods, respectively based on the corresponding elliptic Liouville type theorems and energy estimates

Liouville\u27s theorems for Lévy operators [PDF]

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 ...

$L^p$ Liouville type theorems for harmonic functions on gradient Ricci solitons

In this paper we consider $L^p$ Liouville type theorems for harmonic functions on gradient Ricci solitons. In particular, assume that $(M,g)$ is a gradient shrinking or steady Kähler-Ricci soliton, then we prove that any pluriharmonic function $u$ on $M$
