Abstract
Let X be a smooth projective complex variety, and let G be an algebraic reductive complex group. We define the notion of principal Gsheaf, that generalises the notion of principal Gbundle. Then we define a notion of semistability, and construct the projective moduli space of semistable principal Gsheaves on X. This is a natural compactification of the moduli space of principal Gbundles. This is the announcement note presented by the second author in the conference held at Catania (1113 April 2001), dedicated to the 60th birthday of Silvio Greco. Detailed proofs will appear elsewhere.
