English
If I is a model with corners and R a ring with a ContMDiffRing structure, then the additive group (R,+) carries a Lie group structure compatible with the smooth structure.
Русский
Уadditive-группа кольца R поддерживает структуру Ли, совместимую с гладкой структурой, полученной из ContMDiffRing.
