Abstract
In this paper renormalization group method is applied to quantum wire with impurity. Differential equation for scattering matrix is obtained. This equation determines temperature-dependence of scattering matrix. System of wire with two quantum channels is studied with this method for different values of interaction parameters. It is shown that non-monotonic temperature-dependence of conductance for this system is possible.
