Najati, Abbas, Homomorphisms in quasi-Banach algebras associated with a Pexiderized Cauchy-Jensen functional equation, Acta mathematica Sinica. English series (Print) , 25(9), 2009, pp. 1529-1542
In this paper, we prove the generalized Hyers-Ulam stability of homomorphisms in quasi-Banach algebras associated with the following Pexiderized Jensen functional equation f(x+y2+z).g(x.y2+z)=h(y). This is applied to investigating homomorphisms between quasi-Banach algebras. The concept of the generalized Hyers-Ulam stability originated from Rassias. stability theorem that appeared in his paper: On the stability of the linear mapping in Banach spaces, Proc. Amer. Math. Soc., 72, 297.300 (1978).
