Stability Problems of Quintic Mappings in Quasi-β-Normed Spaces
We investigate the generalized Hyers-Ulam-Rassias stability problem in quasi-β-normed spaces and then the stability by using a subadditive function for the quintic function f:X→Y such that 2f(2x+y)+2f(2x−y)+f(x+2y)+f(x−2y)=20[f(x+y)+f(x−y)]+90f(...
