报告题目：Stability of perturbed norm-additive maps between Banach spaces.

报 告 人：孙龙发副教授，华北电力大学

报告内容：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.
