✦ Synopsis

A generalization of Wilson's local OPE for the short-distance expansion of Euclidean current correlators, called delocalized operator expansion (DOE), which has been proposed recently, is discussed. The DOE has better convergence properties than the OPE and can account for non-local non-perturbative QCD effects.

## Abstract Some expansion and completeness theorems for operator manifolds, which are currently being employed in propagator theory, are derived. It is shown that excitation or ionization operators satisfying the conditions __Q__|0〉 = |Λ〉 and __Q__~Ξ›~|0〉 = 0 for general excited states |Λ〉 and refe
