内容摘要:
In this talk, we first present a sharp universal weakly stable formula for perturbed norm-additive maps between Banach spaces. Making use of it, we give the results about the Qian stability for non-surjective maps and the Hyers-Ulam stability for almost surjective maps. At the end, we present some results about the non-surjective perturbed norm-additive maps between the continuous function spaces.
