On spectral minimal partitions: the case of the sphere
B. Helffer, T. Hoffmann-Ostenhof, S. Terracini
We consider spectral minimal partitions. Continuing work of the the present authors about problems for planar domains, [23], we focus on the sphere and obtain a sharp result for 3-…

Nodal sets of magnetic Schroedinger operators of Aharonov-Bohm type and energy minimizing partitions
Benedetta Noris, Susanna Terracini
In this paper we consider a stationary Schroedinger operator in the plane, in presence of a magnetic field of Aharonov-Bohm type with semi-integer circulation. We analyze the nodal…
