e/Banach measure

Information
has gloss	eng: In mathematics, Banach measure in measure theory may mean a real-valued function on the algebra of all sets (for example, in the plane), by means of which a rigid, finitely additive area can be defined for every set, even when a set does not have a true geometric area. That is, this is a theoretical definition getting round the phenomenon of non-measurable sets. However, as the Vitali set shows, it cannot be countably additive.
