Interval Garside groups arising from involutions in finite reflection groups
Eirini Chavli, Thomas Gobet
We identify and study the interval Garside groups arising from the restriction of the absolute order on a Coxeter group to a lattice , where is an involution. Those in…
Homological algebra of Nakayama algebras and 321-avoiding permutations
Eirini Chavli, Rene Marczinzik
Linear Nakayama algebras over a field are in natural bijection to Dyck paths and Dyck paths are in natural bijection to 321-avoiding bijections via the Billey-Jockusch-Stanley…
The BMM Symmetrising Trace Conjecture for Families of Complex Reflection Groups of Rank Two
Eirini Chavli, Götz Pfeiffer
The exceptional complex reflection groups of rank 2 are partitioned into three families. We construct explicit matrix models for the Hecke algebras associated to the maximal groups…
The center of the walled Brauer algebra
Eirini Chavli, Maud De Visscher, Alison Parker +2
We show that the centre of the walled Brauer algebra over the complex field , for any parameter , is generated by the supersymmetric pol…
