By generalizing the Holstein-Primakoff realization and the Dyson realization of the Lie algebra SU(2),various realizations of the deformed angular momentum algebra Rc0,c1,c2q,s,a five-parameter deformed SU(2) by combi...
Although the asymptotic freedom of nonabelian gauge theory makes it possible to construct a renormalized, perturbatively calculable field theory of interactions, there still remain some perplexities, e.g. strong inter...
