English
The change of form map respects algebra scalars: applying changeForm to the image of an element r ∈ R under algebraMap is the same as algebraMap of r into the target Clifford algebra.
Русский
Изменение формы сохраняет скаляры: применяя changeForm к образу скаляра r через algebraMap, получаем тот же результат, что и algebraMap в целевой алгебре Клиффорда.
