On Pleijel's nodal domain theorem for quantum graphs

Matthias Hofmann, James B. Kennedy, Delio Mugnolo +1

We establish metric graph counterparts of Pleijel's theorem on the asymptotics of the number of nodal domains of the -th eigenfunction(s) of a broad class of operators on…

A variational formulation for Dirac operators in bounded domains. Applications to spectral geometric inequalities

Pedro R. S. Antunes, Rafael D. Benguria, Vladimir Lotoreichik +1

We investigate spectral features of the Dirac operator with infinite mass boundary conditions in a smooth bounded domain of . Motivated by spectral geometric inequali…
