We calculate the conductance of a system of two spinless Luttinger liquidwires with different interaction strengths g_1, g_2, connected through a shortjunction, within the scattering state formalism. Following earlier work weformulate the problem in current algebra language, and calculate the scaledependent contribution to the conductance in perturbation theory keeping theleading universal contributions to all orders in the interaction strength. Fromthat we derive a renormalization group (RG) equation for the conductance. Theanalytical solution of the RG-equation is discussed in dependence on g_1, g_2.The regions of stability of the two fixed points corresponding to conductanceG=0 and G=1, respectively, are determined.
