Virasoro conjecture

In algebraic geometry, the Virasoro conjecture states that a certain generating function encoding Gromov–Witten invariants of a smooth projective variety is fixed by an action of half of the Virasoro algebra. The Virasoro conjecture is named after theoretical physicist Miguel Ángel Virasoro. {{harvs|txt | last3=Xiong | first3=Chuan-Sheng | last2=Hori | first2=Kentaro | last1=Eguchi | first1=Tohru | title=Quantum cohomology and Virasoro algebra | url=https://dx.doi.org/10.1016/S0370-2693(97)00401-2 | doi=10.1016/S0370-2693(97)00401-2 |mr=1454328 | year=1997 | journal=Physics Letters B | issn=0370-2693 | volume=402 | issue=1 | pages=71–80}}

proposed the Virasoro conjecture as a generalization of Witten's conjecture. {{harvs|txt|last=Getzler|first=Ezra|authorlink=Ezra Getzler|year=1999}} gave a survey of the Virasoro conjecture.

The proof of the genus 0 Virasoro conjecture for all smooth projective varieties (or more generally, compact symplectic manifolds) was first given by Xiaobo Liu and Gang Tian (1998).{{Citation |last1=Liu |first1=Xiaobo |title=Virasoro Constraints For Quantum Cohomology |date=1998-10-20 |id=arXiv:math/9806028 |last2=Tian |first2=Gang|arxiv=math/9806028 |bibcode=1998math......6028L }}
