ON I2 AND I2-CONVERGENCE IN ALMOST SURELY OF COMPLEX UNCERTAIN DOUBLE SEQUENCES

Abstract

In this study, we investigate the notions of I2 -converge-nce almost surely (a.s.) and I2-convergence a.s. of complex uncer-tain double sequences in an uncertainty space, and obtain some of their features and identify the relationships between them. In ad-dition, we put forward the concepts of I2 and I2-Cauchy sequence a.s. of complex uncertain double sequences and investigate their relationships.
