摘要：
A spin-1/2 magnetic impurity coupled to a one-dimensional correlated electron system have been studied by applying the density renormalization group method. The Kondo temperature is substantially enhanced by strong repulsive interactions in the chain, but it changes non-monotonically in the case of electron attraction. The magnetization of the impurity at zero-temperature shows local Fermi liquid behavior.
