Spectral asymptotics and estimates for matrix Birman-Schwinger operators with singular measures

Grigori Rozenblum, Grigory Tashchiyan

We consider operators of the form $\mathbf{T}={\mathbf{A}}^{\ast }(V\mu )\mathbf{A}$ in ${\mathbb{R}}^{\mathbf{N}}$, where $\mathbf{A}$ is a pseudodifferential operator of order $-l$, $\mu$ is a co…
