Abstract
The recently discovered first order rotational correction to the nucle on axial-vector coupling constant g(A) within the framework of the chi ral quark soliton model appears to provide us with an unexpectedly sim ple solution to the long-standing g(A) problem in the Skyrme model. A prominent feature of this special type of 1/N-c correction is that the corresponding effect is entirely missing in the Skyrme model. We try to clarify the underlying mathematical reason why such a crucial diffe rence appears between these two intimately-connected effective theorie s of baryons.
