S. Ostadbashi, S. Mahmoudfakhe, M. Solaimaninia

Abstract


In this paper, some stability results concerning the functional equation
f(2x + y) + f(2x - y) = f(x + y) + f(x - y) + f(2x) - 2f(x)
in intuitionistic fuzzy normed spaces are investigated. Also, the intuitionistic fuzzy continuity
of the quadratic and additive functions is dened.
