Research Associate in Mathematics, Dr Matteo Casati, from the School of Mathematics, Statistics and Actuarial Science (SMSAS) at the University of Kent, spoke at the Italian Meeting of Mathematical Physics.

##### Matteo presented a talk in October titled, ‘Poisson cohomology for differential and difference operators’ at the Meeting held in Montecatini Terme, Italy.

**Abstract:**

Integrable partial differential and difference equations can both be written in terms of a suitable class of Poisson brackets – they can be regarded, as in the finite-dimensional case, as defined by Poisson bivectors on some manifold, or as differential, pseudodifferential or shift operators. I will present some results about the cohomology of the Lichnerowicz complex, which plays a fundamental role for classifying not equivalent deformations and compatible brackets.
