A Kirwan blow-up and trees of vector bundles
Guenther Trautmann
In the paper [MTT] a conceptuel description of compactifications of moduli spaces of stable vector bundles on surfaces has been given, whose boundaries consist of vector bundles on…
Equivariant Primary Decomposition and Toric Sheaves
Markus Perling, Guenther Trautmann
We study global primary decompositions in the category of sheaves on a scheme which are equivariant under the action of an algebraic group. We show that equivariant primary decompo…
A Babylonian tower theorem for principal bundles over projective spaces
I. Biswas, I. Coanda, G. Trautmann
We generalise the variant of the Babylonian tower theorem for vector bundles on projective spaces proved by I. Coanda and G. Trautmann (2006) to the case of principal -bundles o…
Horrocks theory and the Bernstein-Gelfand-Gelfand correspondence
I. Coanda, G. Trautmann
We construct an explicit equivalence between a category of complexes over the exterior algebra, which we call HT-complexes, and the stable category of vector bundles on the corresp…
Moduli spaces of decomposable morphisms of sheaves and quotients by non-reductive groups
J. M. Drezet, G. Trautmann
We extend the methods of geometric invariant theory to actions of non--reductive groups in the case of homomorphisms between decomposable sheaves whose automorphism groups are non-…
