This includes a mathematically precise approach to the Kondo effect, which is an example of evolution of one conformally invariant boundary condition into another through boundary conditions which can break conformal invariance, and a proposed mathematical statement of the Kondo effect conjecture. We also review some of the known physical results on WZW boundary conditions from a mathematical perspective.Added explanations of the settings and main resultsHigh Energy Physics - TheoryA mathematical formalism for the Kondo effect in WZW branestext
