The maximum cardinality of minimal inversion complete sets in finite reflection groups
Claudia Malvenuto, Pierluigi Möseneder Frajria, Luigi Orsina +1
We compute for reflection groups of type and for dihedral groups a statistic counting the maximal cardinality of a set of elements in the group whose generalized in…
The adjoint representation inside the exterior algebra of a simple Lie algebra
Corrado De Concini, Paolo Papi, Claudio Procesi
For a simple complex Lie algebra we study the space of invariants , (which describes the is…
Dirac operators and the Very Strange Formula for Lie superalgebras
Victor G. Kac, Pierluigi Moseneder Frajria, Paolo Papi
Using a super-affine version of Kostant's cubic Dirac operator, we prove a very strange formula for quadratic finite-dimensional Lie superalgebras with a reductive even subalgebra.
Symmetries of abelian ideals of Borel subalgebras
Paola Cellini, Pierluigi Moseneder Frajria, Paolo Papi
Elaborating on a paper by Suter, we provide a detailed description of the automorphism group of the poset of abelian ideals in a Borel subalgebra of a finite dimensional complex si…
