SUMMARY:ALG Gravitational Instantons and Hitchin Moduli Spaces
LOCATION:zoom
DESCRIPTION: Abstract: Four-dimensional complete hyperkaehler manifolds can be classifi
 ed into ALE, ALF, ALG, ALG*, ALH, ALH* families.  It has been conjectured t
 hat every ALG or ALG* hyperkaehler metric can be realized as a 4d Hitchin m
 oduli space.  I will describe ongoing work with Rafe Mazzeo, Jan Swoboda, a
 nd Hartmut Weiss to prove a special case of the conjecture, and some conseq
 uences.  The hyperkaehler metrics on Hitchin moduli spaces are of independe
 nt interest, as the physicists Gaiotto–Moore–Neitzke give an intricate conj
 ectural description of their asymptotic geometry.\n \n
