Continuous maps in terms of new convergence conditions

“…Characterizations of continuous maps in terms of convergence of sequences have been given by Garg and Goel [see4,5,6].In this paper, we introduce new convergence conditions S(a) − S(d) in terms of sequences and give analogues and generalizations of the above results of Fuller and Liden.…”
