Symplectic Torelli groups of rational surfaces
Jun Li, Tian-Jun Li, Weiwei Wu
We call a symplectic rational surface \textit{positive} if . The positivity condition of a rational surface is equivalent to the existence of a divisor $D…
Artin presentations, triangle groups, and 4-manifolds
Jack S. Calcut, Jun Li
Gonz{á}lez-Acu{ñ}a showed that Artin presentations characterize closed, orientable -manifold groups. Winkelnkemper later discovered that each Artin presentation determines a smo…
Symplectic isotopy on non-minimal ruled surfaces
Olguta Buse, Jun Li
We prove the stability of for a one-point blow-up of irrational ruled surfaces and study their topological colimit. Non-trivial generators of $π_0[Symp(X,…
A genus-one FJRW invariant via two methods
Jun Li, Wei-Ping Li, Yefeng Shen +1
We calculate a genus-one FJRW invariant of an LG pair via two different methods. In the first method, we apply the cosection localization technique t…
Higher Genus FJRW Invariants of a Fermat Cubic
Jun Li, Yefeng Shen, Jie Zhou
We reconstruct the all-genus Fan-Jarvis-Ruan-Witten invariants of a Fermat cubic Landau-Ginzburg space $(x_1^3+x_2^3+x_3^3: [\mathbb{C}^3/ \mathboldμ_3]\to \mathbb{C})$ from genus-…
Symplectic -spheres and the symplectomorphism group of small rational 4-manifolds, II
Jun Li, Tian-Jun Li, Weiwei Wu
For , let be the number of -symplectic spherical homology classes.We completely determine the Torelli symplectic ma…
