A new type of approximation for cubic functional equations in Lipschitz spaces
(Semnan University, 2020-01-01)Let G be an abelian group with a metric d, E be a normed space and f : G → E be a given function.We define difference C 3,1 f by the formulaC 3,1 f(x,y) = 3f(x + y) + 3f(x − y) + 48f(x) − f(3x + y) − f(3x − ...
