Let G be a finite group, and let A be a finite abelian G-group. 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 H 1 (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.
