Wieler solenoids: non-Hausdorff expansiveness, Cuntz-Pimsner models, and functorial properties
Robin J. Deeley, Menevse Eryüzlü, Magnus Goffeng +1
Building on work of Williams, Wieler proved that every irreducible Smale space with totally disconnected stable sets can be realized via a stationary inverse limit. Using this resu…

Counting Negative Eigenvalues for the Magnetic Pauli Operator
Søren Fournais, Rupert L. Frank, Magnus Goffeng +2
We study the Pauli operator in a two-dimensional, connected domain with Neumann or Robin boundary condition. We prove a sharp lower bound on the number of negative eigenvalues remi…
