The tract path integral solution of the relativistic Aharonov-Bohm-Dyon sys
tem is obtained by summing the perturbation series of a path integral for t
he relativistic systems. Different from an earlier treatment by the author
(2000, Ann. Phys. (N.Y.) 282, 270) based on the famous space-time transform
ation and complicated infinite multiple-valued transformation of Kustaanhei
mo and Stiefel in order to perform the path integral, the procedure develop
ed in this contribution involves: only the explicit form of a simple Green'
s function and an explicit path integral is avoided. (C) 2001 Academic Pres
