Abstract
We calculate the one-loop effective potential for the toroidal non-abe lian D-brane in the constant magnetic SU(2) gauge field. The study of its properties shows that the potential is unbounded below. This fact indicates the instability of the non-abelian D-brane in the background under consideration like the instability of chromomagnetic vacuum in SU(2) gauge theory. (C) 1998 Elsevier Science B.V.
