Queer Poisson brackets on Banach manifolds
It turns out that Poisson brackets on Banach manifolds $M$ defined as a bilinear map from $C^\infty(M)\times C^\infty(M)$ to $C^\infty(M)$ satisfying Leibniz and Jacobi conditions may not be given by Poisson tensors. Their value at some point may depend on higher order derivatives of functions. We present a specific example of such Poisson bracket on $l^p$ spaces. From physical point of view these brackets are pathological, as the Hamiltonian vector fields don't lead to flows on $M$.
The talk is based on joint work with D. Beltita and A.B. Tumpach: https://arxiv.org/abs/1710.03057.
