Abstract:
Motivated by Poisson structures for complex fluids containing cocycles,
such as the Poisson structure for spin glasses given by Holm and
Kupershmidt in 1988, we investigate a general construction of Poisson
brackets with cocycles. Connections with the construction of compatible
brackets found in the theory of integrable systems are also briefly
discussed.
