We present upper estimates for the number of negative eigenvalues of two-dimensional Schroedinger operators with potentials generated by Ahlfors regular measures of arbitrary dimension $\alpha\in (0, 2]$.The estimates are given in terms of the integrals of the potential with a logarithmic weight and of its L $\log$ L type Orlicz norms. In the case $\alpha = 1$, our estimates are stronger than the known ones about Schroedinger operators with potentials supported by Lipschitz curves. 
Eigenvalue estimates and asymptotics for weighted pseudodifferential operators with singular measures in the critical case
In a domain $\Omega\subset \mathbb{R}^{\mathbf{N}}$ we consider a selfadjoint operator $\mathbf{T}=\mathfrak{A}^*P\mathfrak{A} ,$ where $\mathfrak{A}$ is a pseudodifferential operator of order
Calogero Type Bounds in Two Dimensions
For a Schrödinger operator on the plane R with electric potential V and Aharonov–Bohm magnetic field we obtain an upper bound on the number of its negative eigenvalues in terms of the LpRq-norm of V
Lieb–Thirring Estimates for Singular Measures

Thanks to the Birman-Schwinger principle, Weyl’s laws for Birman-Schwinger operators yields semiclassical Weyl’s laws for the corresponding Schrödinger operators. In a recent preprint Rozenblum
Eigenvalues of the Birman-Schwinger operator for singular measures: the noncritical case
In a domain Ω ⊆ R we consider compact, BirmanSchwinger type, operators of the form TP,A = A ∗PA; here P is a singular Borel measure in Ω and A is a noncritical order −l 6= −N/2 pseudodifferential

An upper estimate for the number of negative eigenvalues below the essential spectrum for the magnetic Schrödinger operator with Aharonov-Bohm magnetic field in a strip is obtained. Its further shown
Eigenvalues of singular measures and Connes noncommutative integration
In the recent paper [32] the authors have considered the Birman-Schwinger (Cwikel) type operators in a domain Ω ⊆ R, having the form TP = A∗PA. Here A is a pseudodifferential operator in Ω of order
