Resolutions of De Concini-Procesi ideals indexed by hooks
Riccardo Biagioli, Sara Faridi, Mercedes Rosas
We find a minimal generating set for the De Concini-Procesi ideals indexed by hooks, and study their minimal free resolutions as well as their Hilbert series and regularity.
Colored-Descent Representations of Complex Reflection Groups G(r,p,n)
Eli Bagno, Riccardo Biagioli
We study the complex reflection groups G(r,p,n). By considering these groups as subgroups of the wreath products Z_r wr S_n, and by using Clifford theory, we define combinatorial p…
Tensorial square of the Hyperoctahedral group Coinvariant Space
Francois Bergeron, Riccardo Biagioli
The purpose of this paper is to give an explicit description of the trivial and alternating components of the irreducible representation decomposition of the bigraded module obtain…
Signed Mahonian polynomials for classical Weyl groups
Riccardo Biagioli
The generating functions of the major index and of the flag-major index, with each of the one-dimensional characters over the symmetric and hyperoctahedral group, respectively, hav…
Supersolvable LL-lattices of binary trees
Riccardo Biagioli, Frederic Chapoton
Some posets of binary leaf-labeled trees are shown to be supersolvable lattices and explicit EL-labelings are given. Their characteristic polynomials are computed, recovering their…
