  目:Degenerations and Mirror Symmetry I: the A-model (Gromov-Witten Theory)
  间:2022.08.08(星期一),16:00-18:00
  点:腾讯会议:803-347-490
  要:In this series of talks, I will discuss some aspects of the degeneration technique in mirror symmetry. For the first talk, I will talk about relative Gromov--Witten theory. Relative Gromov--Witten invariants count curves in algebraic varieties with tangency conditions along divisors. Relative Gromov--Witten invariants play a central role in computing Gromov--Witten invariants via the degeneration formula. I talk about structures in relative Gromov--Witten theory and how relative Gromov--Witten theory varies under birational transformations.

  点:腾讯会议:552-123-014
  要:In this series of talks, I will discuss some aspects of the degeneration technique in mirror symmetry. For the second talk, I will talk about relative mirror symmetry, relative periods, and how relative periods and (absolute) periods are related.
