Genus and braid index associated to sequences of renormalizable Lorenz maps

We describe the Lorenz links generated by renormalizable Lorenzmaps with reducible kneading invariant (K−f ,K+f ) = (X, Y ) * (S,W), in termsof the links corresponding to each factor. This gives one new kind of operationthat permits us to generate new knots and links from the ones correspondingto the factors of the -product. Using this result we obtain explicit formulas forthe genus and the braid index of this renormalizable Lorenz knots and links.Then we obtain explicit formulas for sequences of these invariants, associatedto sequences of renormalizable Lorenz maps with kneading invariant (X, Y )*(S,W)^*n, concluding that both grow exponentially. This is specially relevant,since it is known that topological entropy is constant on the archipelagoes ofrenormalization
