Poisson–Nijenhuis structures on quiver path algebras
C Bartocci, A Tacchella - Letters in Mathematical Physics, 2017 - Springer
We introduce a notion of noncommutative Poisson–Nijenhuis structure on the path algebra
of a quiver. In particular, we focus on the case when the Poisson bracket arises from a …
