On Davies' conjecture and strong ratio limit properties for the heat kernel

Yehuda Pinchover

We study strong ratio limit properties and the exact long time asymptotics of the heat kernel of a general second-order parabolic operator which is defined on a noncompact Riemanni…

A ground state alternative for singular Schrödinger operators

Yehuda Pinchover, Kyril Tintarev

Let $a$ be a quadratic form associated with a Schrödinger operator $L = - \nabla \cdot (A \nabla) + V$ on a domain $Ω \subset R^{d}$ . If $a$ is nonnegative on $C_0^…

Existence of minimizers for Schrodinger operators under domain perturbations with application to Hardy's inequality

Yehuda Pinchover, Kyril Tintarev

The paper studies the existence of minimizers for Rayleigh quotients $μ_{Ω} = in f \frac{\int _{Ω} ∣\nabla u ∣ ^{2}}{\int _{Ω} V ∣ u ∣ ^{2}}$ , where $Ω$ is a domain in $R^{N}$ , and $V$ is a non…
