<h2><small><small>"An alternative approach to the Dirac operator via
the Dirichlet to Neumann operator." <br>
<br>
Abstract<br>
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. </small></small></h2>
A presto<br>
