The homotopy Lie algebra of symplectomorphism groups of 3-fold blow-ups of $(S^2\times S^2,{\sigma }_{std}\oplus {\sigma }_{std})$

Sílvia Anjos, Sinan Eden

We consider the 3-point blow-up of the manifold $(S^2\times S^2,\sigma \oplus \sigma )$ where $\sigma$ is the standard symplectic form which gives area 1 to the sphere $S^2$, and study its group…
