Invariant Poisson-Nijenhuis structures on Lie groups and classification

Zohreh Ravanpak, Adel Rezaei-Aghdam, Ghorbanali Haghighatdoost

We study right-invariant (resp., left-invariant) Poisson-Nijenhuis structures on a Lie group $G$ and introduce their infinitesimal counterpart, the so-called r-n structures on the…
