For each subgroup H of G, Ω(H;A) denotes the ring of monomial representations of H with coefficients in A, which is a generalization of the Burnside ring Ω(H) of H. We research the multiplicative induction map Ω(H;A) → Ω(G;A) derived from the tensor induction map Ω(H) → Ω(G), and also research the unit group of Ω(G;A). The results are explained in terms of the first cohomology groups H1(K;A) for K ≤ G. We see that tensor induction for 1-cocycles plays a crucial role in a description of multiplicative induction. The unit group of Ω(G;A) is identified as a finitely generated abelian group. We especially study the group of torsion units of Ω(G;A), and study the unit group of Ω(G) as well.}, title = {Multiplicative induction and units for the ring of monomial representations}, volume = {355}, year = {2019}, yomi = {タケガハラ, ユウゲン} }
