Existence of supremum and infimum in E^- and relations of (M) integral and (G) integra

Existence of supremum and infimum in E^-and relations of (M) integral and (G) integral

Proves the existence of supremum and infimum in the noncompact fuzzy number space E ～, redefines E ～ valued (M) integral, and then discusses the relations between (M) integral and (G) integral of E ～ valued functions.
