In this project we will study vector bundles on algebraic varieties, especially projective spaces, hyperquadrics and grassmanians, through the structure of their cohomology rings. Our starting points are a firm knowledge of the few examples of indecomposable low rank bundles on projective spaces, and the recent work of Eisenbud and Schreyer. The goal are searching for new examples of indecomposable low rank bundles on the varieties mentioned above, as well as a obtaining a deeper understanding of Hartshornes conjecture about vector bundles on projective spaces.
