Brenti, Francesco; Carnevale, Angela Odd length for even hyperoctahedral groups and signed generating functions. (English) Zbl 1370.05010 Discrete Math. 340, No. 12, 2822-2833 (2017). Summary: We define a new statistic on the even hyperoctahedral groups which is a natural analogue of the odd length statistic recently defined and studied on Coxeter groups of types \(A\) and \(B\). We compute the signed (by length) generating function of this statistic over the whole group and over its maximal and some other quotients and show that it always factors nicely. We also present some conjectures.
