DESCRIPTION:Title: <a href="https://researchseminars.org/talk/BOWL/27/">AL
 G Gravitational Instantons and Hitchin Moduli Spaces</a>\nby Laura Fredric
 kson (Oregon) as part of B.O.W.L Geometry Seminar\n\n\nAbstract\nFour-dime
 nsional complete hyperkaehler manifolds can be classified into ALE\, ALF\,
  ALG\, ALG*\, ALH\, ALH* families.  It has been conjectured that every ALG
  or ALG* hyperkaehler metric can be realized as a 4d Hitchin moduli space.
   I will describe ongoing work with Rafe Mazzeo\, Jan Swoboda\, and Hartmu
 t Weiss to prove a special case of the conjecture\, and some consequences.
   The hyperkaehler metrics on Hitchin moduli spaces are of independent int
 erest\, as the physicists Gaiotto—Moore—Neitzke give an intricate conj
 ectural description of their asymptotic geometry.\n
