The main results of this paper give a negative answer to the problem of transformations of the linear non-homogeneous differential equations of order two into a homogeneous one, by means of the internal elements of the non-homogeneous equation. Other results, concerning perturbation by means of a s

## Abstract We show that, in the high‐density limit, restricted Møller‐Plesset (RMP) perturbation theory yields __E__ = π^−2^(1 − ln 2) ln __r__~s~ + __O__(__r__) for the correlation energy per electron in the uniform electron gas, where __r__~s~ is the Seitz radius. This contradicts an earlier der
