Abstract
The recently discovered first order rotational correction to the nucle on axial-vector coupling constant g(A) within the chiral quark soliton model appears to provide us with an unexpectedly simple solution to t he 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 ef fect is entirely missing in the Skyrme model. We try to clarify the un derlying mathematical reason why such a crucial difference appears bet ween the two effective theories of baryons.
