Fuzzy Stability of an Additive-Quadratic-Quartic Functional Equation

Stability of an additive-quadratic-quartic functional equation

“…A. K. Hassan et al [1], M. Mohamadi et al [2] and C. Park et al [3] investigated the stability of the AQQ (additivequadratic-quartic) functional equation where k is a fixed real constant with k ≠ 0, ±1. In this paper, let V and W be real vector spaces and Y be a real Banach space.…”

Fixed Points and Stability of an Aqcq-Functional Equation in G-Normed Spaces

“…has been investigated in [24,33,34]. The stability problems of several functional equations have been extensively investigated by a number of authors and there are many interesting results concerning this problem (see [1,3,7,9,11,15,16], [19,22,23,28,30], [38]- [42]).…”

ADDITIVE-QUADRATIC Ρ-Functional INEQUALITIES IN FUZZY BANACH SPACES

“…Cholewa [9] noticed that the theorem of Skof is still true if the relevant domain E 1 is replaced by an Abelian group. The stability problems of various functional equations have been extensively investigated by a number of authors (see [1,5,6,7,10,17,18,22,25,26,27,29,30,31,32,33,34,38,39]).…”
