In this paper, the concept of asymptotically lacunary I-2-invariat ant equivalence, the concepts of asymptotically lacunary sigma(2)-equivalence and the concept of asymptotically lacunary invariant S-2 -equivalence for double sequences are defined. In addition, some relationships were obtained among these new equivalence concepts.
