Özet

In this paper, we introduce and investigate the concept of ward continuity in 2-normed spaces. A function f defined on a 2-normed space (X,||., .||) is ward continuous if it preserves quasi-Cauchy sequences, where a sequence (xn) of points in X is called quasi-Cauchy if (Formula presented) for every z ∈ X. Some other kinds of continuities are also introduced, and interesting theorems are proved in 2-normed spaces.
