On Bernstein approximants and the φ-variation of a fuzzy random variable

In this paper, we study different properties of Bernstein approximants of a fuzzy random variable, as those in relation with the approximation of fuzzy random variables by means of its n-Bernstein approximant. Moreover, we define and study the concept of phi -variation for a fuzzy random variable. (C) 2001 Elsevier Science Inc. All rights reserved.
