Abstract
A scaling theory is used to show that for temperatures , the properties of the asymmetric Anderson model () are universal functions of the scaling invariants and , where is the conduction electron bandwidth or , whichever is smaller. Crossovers between various regimes of simple behavior as the temperature changes are described. is identified as the criterion for a "mixed-valence" ground state, where the susceptibility . For , there is a local-moment regime with a Kondo temperature .
