Abstract
In this article I discuss some aspects of what is known about correlated electronic wavefunctions, in particular what has been learned from quantum Monte Carlo studies of the homogeneous electron gas. First, I motivate the discussion, then briefly give references to the quantum Monte Carlo methods, discuss the pair product wavefunction and its generalization to backflow and three body wavefunctions. Finally, I conclude with some current difficulties in extending these ideas to electrons in an external potential.
