Note on energy index and first eigenvalue of minimal surfaces in spheres

Matilde Gianocca

A minimal immersion from a surface to can be viewed both as a critical point of the area and of the energy. Although no difference appears at first order, looking at the resp…

Rigidity in the Ginzburg--Landau approximation of harmonic spheres

Matilde Gianocca

We prove that not every harmonic map from to can arise as a limit of Ginzburg--Landau critical points. More precisely, we show that the only degree-one harmonic map…
