摘要：

The existence of distinguished isogenies is proved for formal groups defined over the ring of integers of a local field with ramification index less than the characteristic of the residue field. This generalizes the result of Demchenko for Honda formal groups. Bibliography: 4 titles. © Springer Science+Business Media, Inc. 2007.
