DESCRIPTION:Title: <a href="https://researchseminars.org/talk/EASW/3/">Qua
 ntum Modularity from 3-Manifolds</a>\nby Miranda Cheng (Univ. of Amsterdam
 /National Taiwan University) as part of East Asian String Webinars\n\n\nAb
 stract\nQuantum modular forms are functions on rational numbers that have 
 rather mysterious weak modular properties. Mock modular forms and false th
 eta functions are examples of holomorphic functions on the upper-half plan
 e which lead to quantum modular forms. Inspired by the 3d-3d correspondenc
 e in string theory\, a new topological invariants named homological blocks
  for (in particular plumbed) three-manifolds have been proposed a few year
 s ago. My talk aims to explain the recent observations on the quantum modu
 lar properties of the homological blocks\, as well as the relation to loga
 rithmic vertex algebras. The talk will be based on a series of work in col
 laboration with Sungbong Chun\, Boris Feigin\, Francesca Ferrari\, Sergei 
 Gukov\, Sarah Harrison\, and Gabriele Sgroi.\n
