Graded bimodules over split group algebras: stabilizers and Peirce decompositions
Felipe de Mattos Chafik Hindi, Waldeck Schutzer
We classify, up to graded isomorphism, graded bimodules over split group algebras of finite abelian subgroups of an arbitrary group. The classification is governed by double cosets…
A classification of group gradings on incidence algebras over commutative rings
Felipe de Mattos Chafik Hindi, Waldeck Schutzer
Let be a commutative ring with 1, a locally finite partially ordered set, and a group. We derive necessary and sufficient conditions for an -algebra isomorphism betw…
Atomic Decompositions of Lie Characters and the Dominant Weight Poset
Felipe de Mattos Chafik Hindi, Waldeck Schutzer
Let be a complex semisimple Lie algebra and, for a dominant integral weight , let be the multiplicity-free sum of the weights of the irreducible module $V(λ…
Degree-one Pieri rule for non-symmetric Jack polynomials
Waldeck Schutzer
We give a degree-one Pieri formula for integral nonsymmetric Jack polynomials. In direct analogy with the symmetric case, its coefficients are described by a combinatorial device c…
On some H-Galois objects which are distinguished by their polynomial H-identities
Waldeck Schützer, Abel Gomes de Oliveira
When k is an algebraically closed field of characteristic 0 and H is a non-semisimple monomial Hopf algebra, we show that all Galois objects over H are determined up to H-comodule…
