Eigenfunctions at the threshold energies of magnetic Dirac operators with positive mass
(57K, LaTeX2e)

ABSTRACT.  We propose a framework for supersymmetric 
Dirac operators to have threshold energies. We apply the obtained results 
to magnetic Dirac operators with positive mass in order 
to investigate the asymptotic behaviors at infinity 
of the threshold eigenfunctions. 
It turns out that the results of most of the existing 
works on the zero modes of the Weyl-Dirac operators remain to hold 
for the threshold eigenfunctions of the magnetic Dirac operators 
with positive mass.
