DESCRIPTION:Speaker: Isabella Khan\nhosted by Xujia Chen\nAbstract: The Hee
 gaard Floer d-invariant is a numerical invariant of rational homology sphe
 res which is analogous to the Frøyshov h-invariant from Instanton theory.
  In this talk\, we use Zemke’s recent isomorphism between lattice Floer 
 and Heegaard Floer homology to compute the d-invariant for all rational ho
 mology spheres which arise as negative definite plumbed manifolds\, verify
 ing a 20 year old conjecture of Némethi.
