Scattering by magnetic fields

D. R. Yafaev

Consider the scattering amplitude $s (ω, ω^{'}; λ)$ , $ω, ω^{'} \in S^{d - 1}$ , $λ > 0$ , corresponding to an arbitrary short-range magnetic field $B (x)$ , $x \in R^{d}$ . This…

A trace formula for the Dirac operator

D. R. Yafaev

Our goal is to extend the theory of the spectral shift function to the case where only the difference of some powers of the resolvents of self-adjoint operators belongs to the trac…

Trace-class approach in scattering problems for perturbations of media

D. R. Yafaev

We consider the operators $H_{0} = M_{0}^{- 1} (x) P (D)$ and $H = M^{- 1} (x) P (D)$ where $M_{0} (x)$ and $M (x)$ are positively definite bounded matrix-valued functions and $P (D)$ is an ellip…
