The Eigenvalue Sum for a One-Dimensional Potential
(178K, AMSTeX)
ABSTRACT. We obtain a sharp WKB expansion for the sum of the
negative eigenvalues of a Schr\"odinger
operator in one dimension. This is part 4
in the saga of 7 papers devoted to the proof
of the $Z^{5/3}$-term in the atomic energy asymptotics.
