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 main result is that it can be extended to arbitrary
double quasi-Poisson brackets. We also provide an alternative construction for
the double quasi-Poisson brackets of Van den Bergh associated to quivers, and
of Massuyeau-Turaev associated to the fundamental groups of surfaces.Comment: 37pages, 1 figure, including 4 appendices. v2 : minor changes,
