Abstract: |
It is well known that every vector bundle on the projective space P^n admits a resolution by vector bundles which are direct sums of the line bundles O(i). A celebrated theorem of Beilinson implies that one can do better: every vector bundle can be fully described in terms of the line bundles O, O(1), …, O(n). More precisely, he showed that the latter form a so called full exceptional collection in the derived category of P^n. Later Kapranov found a similar collection of vector bundles on Grassmannians. A long standing conjecture states that one construct such a collection on any rational homogeneous variety; in particular, on orthogonal and isotropic Grassmannians. We will discuss the mentioned results and show how to prove this conjecture for Lagrangian Grassmannians. |
