    The construction of Skyrmions from instantons is due to

    The relation between skyrmions, instantons, calorons, solitons and monopoles is usefully reviewed and further developed in

    added pointer to this review:

    If one assumes confinement, then [[SU(N)]]-QCD is equivalent to a theory of mesons (and glueballs) in which the (quartic) meson coupling constant is 1/N1/N.

    [..][..]

    [[here to stress that]] QCD is equivalent for any NN, including N=3N=3, to a meson theory in which 1/N1/N is the coupling constant, Large N is special only in that the meson coupling is only moderately weak.

    [..][..]

    These considerations remove all of the obstacles to interpreting baryons as the solitons of meson physics

    [..][..]

    There is every evidence that Skyrmions physics with varying couplings reproduces QCD baryons of varying NN.
