DESCRIPTION:Title: <a href="https://researchseminars.org/talk/AnLy/37/">On
  the moduli space curvature at infinity</a>\nby Fernando Marchesano (IFT\,
  Madrid) as part of AnLy Strings and Fields online seminars\n\n\nAbstract\
 nWe analyse the scalar curvature of the vector multiplet moduli space M(VM
 \,X) of type IIA string theory compactified on a Calabi--Yau manifold X. W
 hile the volume of M(VM\,X) is known to be finite\, cases have been found 
 where the scalar curvature diverges positively along trajectories of infin
 ite distance. We classify the asymptotic behaviour of the scalar curvature
  for all large volume limits within M(VM\,X)\, for any choice of X\, and p
 rovide the source of the divergence both in geometric and physical terms. 
 Geometrically\, there are effective divisors whose volumes do not vary alo
 ng the limit. Physically\, the EFT subsector associated to such divisors i
 s decoupled from gravity along the limit\, and defines a rigid N=2 field t
 heory with a non-vanishing moduli space curvature $R_{rigid}$. We propose 
 that the relation between scalar curvature divergences and field theories 
 that can be decoupled from gravity is a common trait of moduli spaces comp
 atible with quantum gravity.\n
