Personal profile
Research
I am interested in Spectral Theory, in particular for magnetic Schrödinger operators. I am in particular intrerested in how the lower part of the spectrum varies with field strenghts, and semi-classical effects.
I have also worked a bit on nodal domains, in particular with estimating the number of them for the Laplace opeartor, and the influence of boundary conditions.
