Abstract
We study the well-posedness of autonomous parabolic Dirichlet problems involving Schrödinger type operators of the form
with \(\alpha \ge 0\), \(a<0\) and \(b,c\in \mathbb {R}\), in regular unbounded domains \(\Omega \subset \mathbb {R}^N\) containing 0. Under suitable assumptions on \(\alpha \), b and c, the solution is governed by a contractive and positivity preserving strongly continuous (analytic) semigroup on the weighted space \(L^p(\Omega , d\mu (x))\), \(1<p<\infty \), where \(d\mu (x)=(1+|x|^\alpha )^{-1}dx\). The proofs are based on some \(L^p\)-weighted Hardy’s inequality and perturbation techniques.
