Abstract
In this paper, we first consider the critical order Hardy–Hénon type equations and inequalities
where \(n\ge 4\) is even, \(-\infty<a<n\), and \(1<p<+\infty \). We prove Liouville theorems (Theorems 1.1 and 1.3), that is, the unique nonnegative solution is \(u\equiv 0\). Then as an immediate application, by applying method of moving planes in a local way, blowing-up techniques and the Leray–Schauder fixed point theorem, we derive a priori estimates and hence existence of positive solutions to critical order Lane–Emden equations in bounded domains (Theorems 1.4 and 1.6). Extensions to super-critical order Hardy–Hénon type equations and inequalities will also be included (Theorems 1.8 and 1.11). In critical and super-critical order Hardy–Hénon type inequalities, there are no growth conditions on the nonlinearity f(x, u) w.r.t. u and hence the nonlinear term can grow exponentially (or even faster) on u (Theorems 1.3, 1.8 and Remark 1.10).
