Let A be a self-adjoint operator acting over a space X endowed with a partition. We give lower bounds on the energy of a mixed state ρ from its distribution in the partition and the …
We consider the eigenvalues of the magnetic Laplacian on a bounded domain Ω of R 2 with uniform magnetic field β> 0 and magnetic Neumann boundary conditions. We find upper …

We consider the magnetic Dirichlet Laplacian with constant magnetic field on domains of finite measure. First, in the case of a disk, we prove that the eigenvalue branches with …

We give an improvement of sharp Berezin type bounds on the Riesz means $\sum_k (\Lambda-\lambda_k) _+^\sigma $ of the eigenvalues $\lambda_k $ of the Dirichlet …
