The Ulam Type Stability of a Generalized Additive Mapping and Concrete Examples
We give an Ulam type stability result for the following functional equation: f(αx−αx′+x0)=βf(x)−βf(x′)+y0 (for all x,x′∈X) under a suitable condition. We also give a concrete stability result for the case taking up δ∥x∥p∥x′∥q as a control function.
