Anti-symplectic involutions for Lagrangian spheres in a symplectic quadric surface
Published 20 Apr 2021 in math.SG and math.GT | (2104.10007v1)
Abstract: We show that the space of anti-symplectic involutions of a monotone $S2\times S2$ whose fixed points set is a Lagrangian sphere is connected. This follows from a stronger result, namely that any two anti-symplectic involutions in that space are Hamiltonian isotopic.
