During the last years new methods for the description
of the electronic structure of correlated materials
have been developed. The combination of dynamical mean
field techniques with density functional theory
allows for the calculation of electronic properties
of materials from first principles, taking into account
the effect of strong Coulomb interactions.
We will describe some recent advances on transition
metal compounds, in particular on VO2.
Finally, we will also give a critical account
of the LDA+DMFT technique and its shortcomings
and discuss perspectives of how to go beyond.
