Jordan measure

In mathematics, the Peano–Jordan measure (also known as the Jordan content) is an extension of the notion of size (length, area, volume) to shapes more complicated than, for example, a triangle, disk, or parallelepiped. in each have a Jordan measure of 0, while , a countable union of them, is not Jordan-measurable. For this reason, some authors prefer to use the term Jordan content (see the article on content). The Peano-Jordan measure is named after its originators, the French mathematician Camille Jordan, and the Italian mathematician Giuseppe Peano.
