abstract: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.
Asone ofapplications, theJordan decompositiontheorem of a properlydefined signed vector-valuedmeasure is obtained, and the signed vector-valued measureis just afuzzynumber-valuedmeasure.
What Nike said, when it signed Michael Jordan, is that the ultimate measure of any competitor is something else entirely: How irresistible his story is.
