Abstract
We study the effect of dynamical gauge field on the Kaplan's chiral fe rmion on a boundary in the strong gauge coupling limit in the extra di mension. To all orders of the hopping parameter expansion, we prove ex act parity invariance of the fermion propagator on the boundary. This means that the chiral property of the boundary fermion, which seems to survive even in the presence of the gauge field from a perturbative p oint of view, is completely destroyed by the dynamics of the gauge fie ld.
