DESCRIPTION:Title: <a href="https://researchseminars.org/talk/LAGOON/66/">
 The sphere of spherical objects</a>\nby Asilata Bapat (Mathematical Scienc
 es Institute\, ANU Canberra\, Australia) as part of Longitudinal Algebra a
 nd Geometry Open ONline Seminar (LAGOON)\n\n\nAbstract\nConsider the 2-Cal
 abi--Yau triangulated category arising from the zigzag algebra of the An q
 uiver. The braid group acts on this category by twists in spherical object
 s. Given a Bridgeland stability condition\, we describe how to realise the
  spherical objects as a dense subset of a piecewise-linear manifold. This 
 manifold is canonically associated to the category\, and the braid group a
 cts on it piecewise-linearly. We also describe how the manifold transforms
  under wall-crossings of the stability condition. The talk is based on joi
 nt work with Anand Deopurkar and Anthony M. Licata.\n\nZOOM Meeting Link\n
