Rank 4 vector bundles on the quintic threefold

Carlo Madonna (2005)

Open Mathematics

Similarity:

By the results of the author and Chiantini in [3], on a general quintic threefold X⊂P 4 the minimum integer p for which there exists a positive dimensional family of irreducible rank p vector bundles on X without intermediate cohomology is at least three. In this paper we show that p≤4, by constructing series of positive dimensional families of rank 4 vector bundles on X without intermediate cohomology. The general member of such family is an indecomposable bundle from the extension...

Fat bundles and formality

Wojciech Andrzejewski, Aleksy Tralle (1997)

Annales Polonici Mathematici

Similarity:

We prove the formality property of total spaces of fat bundles over compact homogeneous spaces. Some rational homotopy obstructions to fatness are obtained.
