Soft-Gluon Resummation: a Short Review

Abstract

I briefly summarize some general features of soft-gluon contribution to inclusive cross-sections. The discussion includes the issue of soft-gluon singularities in infrared- and collinear-safe observables. All-order resummation and the ensuing varieties of QCD predictions are illustrated.
