  The influence of local electronic correlations on the properties of colossal
magnetoresistance manganites is investigated. To this end, a ferromagnetic
two-band Kondo lattice model is supplemented with the local Coulomb repulsion
missing in this model, and is analyzed within dynamical mean-field theory.
Results for the spectral function, optical conductivity, and the
paramagnetic-to-ferromagnetic phase transition show that electronic
correlations have drastic effects and may explain some experimental
observations.
