English
If S acts compatibly with A and M, the SMulCommClass structures propagate to Derivation(R,A,M) and to Derivation(S A M).
Русский
Если скалярное действие совместимо с A и M, то SMulCommClass переносится на Derivation(R,A,M).
LaTeX
$$$\text{SMulCommClass } S A M \Rightarrow \text{SMulCommClass } S T (\mathrm{Derivation}(R,A,M))$ for appropriate T.$$
