Abstract
We study valence fluctuation at finite temperatures in the periodic Anderson model with the Coulomb interaction between and conduction electons, combining dynamical mean-field theory with the non-crossing approximation. It is found that a large Coulomb repulsion induces a first-order valence transition. The finite temperature phase diagram is determined.
