Abstract
This paper showed a short characterization of the convex combi- nation operation introduced by Zadeh to fuzzy sets. We proved some properties and established two basic results (existence and uniqueness) in the representation of a fuzzy set as a convex combination. Our the- ory was based on the fact that a closed interval [a, b] of real numbers is a convex set, and the fact that a straight-line function from [0, 1] into [a, b] is surjective always, and additionally, it is injective if a <b. We showed some examples in order to illustrate our ideas.
