A function defined on a subset E of X is called strongly lacunary delta-ward continuous if it preserves N-theta-delta-quasi-Cauchy sequences, i.e. (f(x(k))) is an N-theta-delta-quasi-Cauchy sequence whenever (x(k)) is. In this study we obtain some theorems related to strongly lacunary delta-quasi-Cauchy sequences.eninfo:eu-repo/semantics/openAccessStrongly Lacunary Ward ContinuityQuasi-Cauchy SequencesContinuity2-Normed SpaceArticle202719538WOS:000496299300015N/A
