Abstract
The paper presents a summary of some recent work on a SU(5) grand unification scheme for effective 3 + 1 dimensional fields dynamically localized on a domain-wall brane. This is achieved through the confluence of the clash-of-symmetries mechanism for symmetry breaking through domain-wall formation and the Dvali-Shifman gauge boson localization idea. It is shown that it requires an E6 invariant action, yielding a domain-wall solution that has E6 broken to differently embedded SO(10) ⊗ U(1) subgroups in the two bulk regions on the opposites of the wall.
