Relativistic hydrogenic atoms in strong magnetic fields
(568K, Postscript)

ABSTRACT.  In the Dirac operator framework we characterize and estimate the  
ground state energy of relativistic hydrogenic atoms in a constant  
magnetic field and describe the asymptotic regime corresponding to a  
large field strength using relativistic Landau levels. We also define  
and estimate a critical magnetic field beyond which stability is lost.
