摘要
We show that the exact exchange-only Kohn-Sham spin polarized potential Vxσ satisfies a simple condition which leads to the generalizations of Koopman's and Janak's theorems, as well as a simple formula for the integer discontinuity in Vxσ. The generalization of these results for an arbitrary Exc[}ψiσ{] is presented. © 1990.
