Restriction and Induction of Divisors, we want to extend the ordinary restriction and the ordinary induction between the .and the OK-modules, to a restriction and an induction between the divisors of . and . on A. First of all, we clearly have . C .. and therefore we have a unique linear map

Local Pointed Groups on ,-interior ,-algebras,ows from Theorem 5.11 that we can find an inductively complete .-interior G-algebra ., together with a divisor w of . on . such that . ≈ .., so that all the questions concerning induction and restriction of divisors can be discussed in .. Hence, without loss of generality we may assume that . is inductively complete.
