Some results on the higher-rank graphs associated to crystals of semisimple Lie algebras
Marco Matassa
In this paper we continue the study of the higher-rank graphs associated to finite-dimensional complex semisimple Lie algebras, introduced by the author and R. Yuncken, whose const…

The Einstein condition for quantum irreducible flag manifolds
Marco Matassa
We show that any quantum irreducible flag manifold satisfies an analogue of the Einstein condition, expressing proportionality between the Ricci tensor and the metric, at least in…

Equivariant quantizations of the positive nilradical and covariant differential calculi
Marco Matassa
Consider a decomposition of the positive nilradical of a complex semisimple Lie algebra of rank , where each…
