Abstract

We define the generalized Burnside algebra HB(Wn)HB(W_{n}) for BnB_{n}-type Coxeter group WnW_{n} and construct an surjective algebra morphism between Mantaci-Reutenauer algebra (Wn){\sum}'(W_{n}) and HB(Wn)HB(W_{n}). Then, by obtaining the primitive idempotents (eλ)λDP(n)(e_{\lambda})_{\lambda \in \mathcal{DP}(n)} of HB(Wn)HB(W_{n}), we consider the image resWAWneB\textrm{res}_{W_{A}}^{W_{n}}e_{B} and indWAWneBA\textrm{ind}_{W_{A}}^{W_{n}}e_{B}^{A} under restriction and induction map between generalized Burnside algebras. We give an alternative formula to compute the elements number of conjugate classes of WnW_{n}. We also obtain an effective method to determine the size of C(Sn)\mathcal{C}(S_{n}) which is the set of elements of type SnS_{n}.
