Scalar restriction for formal groups

The aim of this work is to generalize the results on the scalar restriction functor for formal groups stated in the paper “Explicit classification of formal groups over local fields” by the first two authors. These results are extended to formal groups over an arbitrary commutative ring, which we assume to be an integral domain or a ring of characteristic zero if necessary. Bibliography: 6 titles.
