Finite-dimensional pointed Hopf algebras over finite simple groups of Lie type V. Mixed classes in Chevalley and Steinberg groups

Nicolás Andruskiewitsch, Giovanna Carnovale, Gastón Andrés García

We show that all classes that are neither semisimple nor unipotent in finite simple Chevalley or Steinberg groups different from $PS{L}_n(q)$ collapse (i.e. are never the support of…
