مستخلص: Abstract Let G be a finite group, and C be an abelian group. We introduce the notions of C -monomial G -sets and C -monomial G -posets, and state some of their categorical properties. This gives in particular a new description of the C -monomial Burnside ring B C (G). We also introduce Lefschetz invariants of C -monomial G -posets, which are elements of B C (G). These invariants allow for a definition of a generalized tensor induction multiplicative map T U , λ : B C (G) → B C (H) associated to any C -monomial (G , H) -biset (U , λ) , which in turn gives a group homomorphism B C (G) × → B C (H) × between the unit groups of C -monomial Burnside rings.
