Carissimi,
vi segnalo il prossimo seminario di ED a Tor Vergata:
Martedi' 16 Dicembre 2014, h 14:30, Aula Dal Passo
Marta Nolasco (Università dell' Aquila)
"An alternative approach to the Dirac operator via the Dirichlet to
Neumann operator."
Abstract
We use the Foldy- Wouthuysen unitary transformation to transform the
Dirac equations into an elliptic problem in the 4-dim half space
with Neumann boundary condition. Then we give an alternative min-max
characterization of the eigenvalues problem for the Brown Ravenhall
one electron atoms Hamiltonian.
A presto
Daniele Castorina
