Abstract
In the last few years significant theoretical progress has been made in our understanding of the physics and quality of Gutzwiller-type variational wave functions for correlated Fermi systems. In particular, new analytic techniques are now available that allow for exact evaluations of expectation values. A brief review of the state-of-the-art is presented.
