DESCRIPTION:Abstract: The Maulik-Nekrasov-Okounkov-Pandharipande correspo
 ndence predicts an equivalence between the partition functions of (numeric
 al) Gromov-Witten and (numerical) Donaldson-Thomas invariants of compact t
 hreefolds. It was recently proposed by Pardon a solution of this conjectur
 al correspondence by reducing to the simpler case of local curves\, which 
 are more amenable for computations by means of TQFT methods. Even more rec
 ently\, inspired by the seminal work of Nekrasov-Okounkov on the index in 
 M-theory\, Brini-Schuler proposed a refined GW/DT correspondence. In this 
 talk\, I will present a full solution for the Donaldson-Thomas side of the
  refined GW/DT correspondence in the case of local curves. In particular\,
  I will explain how to derive the refined DT partition function without re
 lying on degeneration techniques and TQFT methods\, and how our formulas r
 ecover string-theoretic prediction of Aganagic-Schaeffer.\n\nhttps://indic
