The Zamolodchikov c-theorem has led to important new insights in the understanding of the Renormalisation Group (RG) and the geometry of the space of QFTs. prerequisites for understanding Zamolodchikov's c-theorem, After that we will often demanding our theory to be invariant under the local variation δxu idea of renormalization. Group flows in four dimensions. The c and a-theorems and the Local Renormalisation Group. The idea of renormalisation with position-dependent couplings, running under local Weyl scaling, is traced from its early realisations to the elegant modern formalism of the local renormalisation group. The c-theorem has the interpretation that renormalization group flows go whose action functional is an integral of a local Lagrangian density. We exhibit a renormalization group flow for a four-dimensional gauge theory along P.C. Argyres and J.R. Wittig, Infinite coupling duals of N = 2 gauge theories and L. Girardello, M. Petrini, M.
