Non self-adjoint perturbations of the Heisenberg sublaplacian
Luca Fanelli, Luz Roncal, Nico Michele Schiavone
We prove uniform resolvent estimates in weighted -spaces for the sublaplacian on the Heisenberg group . The proof are based on multiplier methods,…
Keller-type bounds for Dirac operators perturbed by rigid potentials
Haruya Mizutani, Nico Michele Schiavone
In this paper we are interested in generalizing Keller-type eigenvalue estimates for the non-selfadjoint Schrödinger operator to the Dirac operator, imposing some suitable rigidity…
Localization of eigenvalues for non-self-adjoint Dirac and Klein-Gordon operators
Piero D'Ancona, Luca Fanelli, David Krejcirik +1
This note aims to give prominence to some new results on the absence and localization of eigenvalues for the Dirac and Klein-Gordon operators, starting from known resolvent estimat…
Eigenvalue bounds for non-selfadjoint Dirac operators
Piero D'Ancona, Luca Fanelli, Nico Michele Schiavone
In this work we prove that the eigenvalues of the -dimensional massive Dirac operator , , perturbed by a possibly non-Hermitian potential , are loca…
