description The Generalized Slater-Jastrow trial functional is a modification of the Slater-Jastrow functional where, effectively, the argument of the Jastrow factor can be momentum dependent. The associated Euler equations, which provide an alternative to the usual approach via perturbation theory, are solved to yield the firs three terms of the electron correlation energies for the two and three dimensional electron gas at high density. In two dimensions we find -0.4039 -0.50 r log r plus an estimated -0.87 r Ry. For three dimensions we find 0.0622 log r -0.082 + 0.059 r log r plus an estimated -0.015 r Ry, where r is the applicable Seitz radius in each case.
