Free subgroup of the C0 symplectic mapping class group
Abstract
Using the technology of barcodes and previously proven continuity results, we extend to C0 symplectic topology a beautiful result from Keating. Given two Lagrangian spheres in a Liouville domain, with good conditions, we prove that the Dehn twists about these spheres generate a free subgroup of the C0 symplectic mapping class group.
