In this paper, we introduce the concept of Phi -contractor in fuzzy normed
spaces and prove the existence and uniqueness theorems of solutions for set

or. As applications of these theorems, we obtain some new fixed point theor
ems in fuzzy normed spaces. (C) 2001 Elsevier Science B.V. All rights reser
