On the decomposition of Betti tables of curves on rational normal surface scrolls

In this talk, we study the minimal free resolution of divisors on a smooth rational normal surface scroll S = S(a1,a2) ⊂¶r.

Our main result provides a nice decomposition of the Betti tables of divisors into much simple Betti tables under the suitable conditions.
