SUMMARY:Differential Geometry Working Seminar | Faisal Romshoo | Torsion-fr
 ee\nhypersymplectic structures
CLASS:PUBLIC
DESCRIPTION:FAISAL ROMSHOO (UNIVERSITY OF WATERLOO)\n\n_Torsion-free hypers
 ymplectic structures_\n\nWe know that a torsion-free \\(\\mathrm{G}_2-\\)s
 tructure determines a\nRiemannian metric with holotomy contained in \\(\\m
 athrm{G}_2\\).\nHowever\, a torsion-free hypersymplectic structure in dime
 nsion \\($4$\\)\nis not necessarily a hyperkähler structure. We will look
  at a\ncounterexample and see under what conditions does a torsion-free\nh
 ypersymplectic structure determine a hyperkähler structure.\n\nMC 5417
