Magnetic Steklov problem on surfaces
Mihajlo CekiÄ, Anna Siffert
The magnetic Dirichlet-to-Neumann map encodes the voltage-to-current measurements under the influence of a magnetic field. In the case of surfaces, we provide precise spectral asym…

Calderón problem for systems via complex parallel transport
Mihajlo CekiÄ
We consider the Calderón problem for systems with unknown zeroth and first order terms, and improve on previously known results. More precisely, let be a compact Riemanni…

Semiclassical analysis on principal bundles
Mihajlo CekiÄ, Thibault Lefeuvre
Let be a compact Lie group. We introduce a semiclassical framework, called Borel-Weil calculus, to investigate -equivariant (pseudo)differential operators acting on -prin…
