Abstract
It is a basic fact in infinite-dimensional Lie theory that the unit group $A^\times $ of a continuous inverse algebra $A$ is a Lie group. We describe criteria ensuring that the Lie group $A^\times $ is regular in Milnor's sense. Notably, $A^\times $ is regular if $A$ is Mackey-complete and locally m-convex.
