Symplectic rigidity and weak commutativity
S. Vazzoler, F. Cardin
An alternative proof of Eliashberg-Gromov's C^0-rigidity theorem is presented and a new notion of weak Lie brackets for Hamiltonian vector fields is proposed and compared.

On C^0-variational solutions for Hamilton-Jacobi equations
Olga Bernardi, Franco Cardin
For evolutive Hamilton-Jacobi equations, we propose a refined definition of C^0-variational solution, adapted to Cauchy problems for continuous initial data. In this weaker framewo…
