Charged particle motion in a strong magnetic field: Applications to plasma confinement
Ugo Boscain, Wadim Gerner
We derive the zero order approximation of a charged particle under the influence of a strong magnetic field in a mathematically rigorous manner and clarify in which sense this appr…

Optimal metrics for the first curl eigenvalue on 3-manifolds
Alberto Enciso, Wadim Gerner, Daniel Peralta-Salas
In this article we analyze the spectral properties of the curl operator on closed Riemannian 3-manifolds. Specifically, we study metrics that are optimal in the sense that they min…

Existence of optimal domains for the helicity maximisation problem among domains satisfying a uniform ball condition
Wadim Gerner
In the present work we present a general framework which guarantees the existence of optimal domains for isoperimetric problems within the class of -regular domains satisf…
