Infinitesimal form boundedness and Trudinger's subordination for the Schrödinger operator

V. G. Maz'ya, I. E. Verbitsky

We give explicit analytic criteria for two problems associated with the Schrödinger operator $H=-\Delta +Q$ on $L^2({\mathbb{R}}^n)$ where $Q\in D^{\prime }({\mathbb{R}}^n)$ is an arbitrary real- or complex-value…
