DESCRIPTION:Speakers: Georg Oberdieck (Heidelberg)\n\nAbstract: Under a s
 uitable primitive assumption\, moduli spaces of stable sheaves on Enriques
  surfaces are smooth projective varieties with torsion canonical bundle\, 
 which were proven by Beckmann and Nuer-Yoshioka to be birational to Hilber
 t schemes of points on the Enriques or compactified Jacobians (depending o
 n whether the dimension is even or odd). While in the even-dimensional ca
 se this determines their Betti numbers\, not much is known in the odd-dime
 nsional case (b_1\,b_2 was computed by Sacca). In this talk I will give an
  overview about recent curve counting results on the local Enriques surfa
 ces and explain what they predict for the moduli spaces of sheaves. In par
 ticular\, we will state a conjectural relation how the perverse Hodge numb
 ers of the compactified Jacobians are determined by their Betti numbers\, 
 and give an asymptotic formula for their Betti numbers. \n\nhttps://math-
