%0 Journal Article %T A New Fixed Point Theorem and a New Generalized Hyers-Ulam-Rassias Stability in Incomplete Normed Spaces %J Mathematics | An Open Access Journal from MDPI %D 2019 %R https://doi.org/10.3390/math7111117 %X In this study, our goal is to apply a new fixed point method to prove the Hyers-Ulam-Rassias stability of a quadratic functional equation in normed spaces which are not necessarily Banach spaces. The results of the present paper improve and extend some previous results. View Full-Tex %U https://www.mdpi.com/2227-7390/7/11/1117
