Sobolev spaces and Bochner Laplacian on complex projective varieties and stratified pseudomanifolds

Let $V\subset \mathbb{C}\mathbb{P}^n$ be an irreducible complex projective variety of complex dimension $v$ and let $g$ be the K\"ahler metric on $\reg(V)$, the regular part of $V$, induced by the Fubini Study metric of $\mathbb{C}\mathbb{P}^n$. In this setting Li and Tian proved that $W^{1,2}_0(\reg(V),g)=W^{1,2}(\reg(V),g)$, that the natural inclusion $W^{1,2}(\reg(V),g)\hookrightarrow L^2(\reg(V),g)$ is a compact operator and that the heat operator associated to the Friedrich extension of the scalar Laplacian $\Delta_0:C^{\infty}_c(\reg(V))\rightarrow C^{\infty}_c(\reg(V))$, that is $e^{-t\Delta_0^{\mathcal{F}}}:L^2(\reg(V),g)\rightarrow L^2(\reg(V),g)$, is a trace class operator. The goal of this paper is to provide an extension of the above result to the case of Sobolev spaces of sections and symmetric Schr\"odinger type operators with potential bounded from below where the underling riemannian manifold is the regular part of a complex projective variety endowed with the Fubini-Study metric or the regular part of a stratified pseudomanifold endowed an iterated edge metric.
