摘要：

The Kondo effect is studied using current algebra techniques which allow a separation of charge and spin degrees of freedom. An algebraic interpretation of the low-temperature fixed point is obtained. The Wilson ratio is shown to be the ratio of the specific heat for the total system to that of the spin sector which is expressed in terms of the conformal anomaly parameter of a Kac-Moody theory. © 1990.
