Abstract: In this paper, our aim is to introduce and study some new spaces of lacunary I - convergence for sequence of fuzzy real number which are defined by compact operator (T) on the real space ℝ . i.e., cFIθ(T), cF0Iθ(T), ℓF∞Iθ(T), ℓF∞θ(T) and examine some basic properties and prove some inclusions relation on these spaces.

Keywords: Ideal, I_θ—convergence, I_θ—Cauchy, fuzzy number, lacunary sequence, compact operator
