Partially hyperbolic symplectomorphism with C^1 bundles
Eramane Bodian, Khadim War
We prove dynamical coherence for partial hyperbolic symplectomorphism in dimension 4 whose stable and unstable bundles are C^1.

Finite Time Hyperbolic Coordinates
Stefano Luzzatto, Dominic Veconi, Khadim War
We define finite-time hyperbolic coordinates, describe their geometry, and prove various results on both their convergence as the time scale increases, and on their variation in th…
