E, Section of Mathematics and Informatics, National and Capodistrian University of Athens, Athens, GreeceJournal Article20170404In this paper, we investigate the general solution and the generalized Hyers-Ulam stability of a new functional equation satisfied by $f(x) = x^{24}$, which is called quattuorvigintic functional equation in intuitionistic fuzzy normed spaces by using the fixed point method.<br />These results can be regarded as an important extension of stability results corresponding to functional equations on normed spaces.http://ijfs.usb.ac.ir/article_4112_9e5015acd2778f77d1a88682726ee364.pdf
