Abstract
The authors extend previous functional integral approaches to the Anderson lattice in the boson representation by taking into account gaussian fluctuations. They extract a contribution to the specific heat proportional to alpha T3 ln T at low T. The sign of alpha is positive in the Kondo limit and mod alpha mod decreases on approaching the mixed-valence regime.Keywords
