Double quasi-Poisson brackets : fusion and new examples [PDF]

open access: yes, 2020
We exhibit new examples of double quasi-Poisson brackets, based on some classification results and the method of fusion. This method was introduced by Van den Bergh for a large class of double quasi-Poisson brackets which are said differential, and our ...
