“…Yoshida introduced a theory of generalized Burnside ring (GBR for short) with respect to a family of subgroups of G (see [10]). In 2015, the study of the unit group of the GBR relative to a collection of G was started by Idei and Oda (see [2]). Also it is discussed by [4] and [5].…”
In this paper, we describe the structure of the direct product of partial Burnside rings of relative to the collection of a finite group. In particular, we t the unit group of the partial Burnside ring relative to the set of all parabolic subgroups of a reducible finite Coxeter group is isomorphic to the direct product of unit groups of the partial Burnside ring of irreducible Coxeter group.

“…The unit group Ω(G) × of the Burnside ring Ω(G) is studied in many papers (see, e.g., [6,9,11,15,18,19,20,24,30,32]). Section 6 is devoted to a review of some well-known facts about Ω(G) × .…”
“…Recently, in [7], Idei and the first author have given a formula of a non-identity unit of Ω(S n , Y n ) which is described in terms of the Möbius function μ Y n on the poset (Y n , ≤) (see Eq. (2)).…”

The unit group of a partial Burnside ring relative to the Young subgroups of the symmetric group S n on n letters is included in the image by the tom Dieck homomorphism. As a consequence of this fact, the alternating character ν n of S n is expressed explicitly as a Z-linear combinations of permutation characters associated with finite left S n -sets S n /Y for the Young subgroups Y .
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
