Quiver Gauge Theories: Finitude and Trichotomoty
D-brane probes, Hanany-Witten setups and geometrical engineering stand as a trichotomy of standard techniques of constructing gauge theories from string theory.Meanwhile, asymptotic freedom, conformality and IR freedom pose as a trichotomy of the beta-function behaviour in quantum field theories.Parallel thereto is a trichotomy in set theory read m
