DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QASTM/14/">K
 3 metrics</a>\nby Max Zimet (Center for the Fundamental Laws of Nature Hig
 h Energy Theory Group and Black Hole initiative fellow\, Harvard Universit
 y\, Boston\, USA) as part of Quantum Aspects of Space-Time and Matter\n\n\
 nAbstract\nI will explain the recent physically motivated construction of 
 Ricci-flat K3 metrics in 2006.02435\, which gives the first examples of Ri
 cci-flat metrics on compact non-toroidal Calabi-Yau manifolds. I will also
  relate it — both physically and mathematically — to a second such con
 struction\, which is as yet not completely explicit: the missing data is t
 he BPS index of a little string theory on $T^2$. In particular\, I will sh
 ow that these discrete invariants may be extracted from the metrics produc
 ed by the first approach.\n
