Abstract:
In this paper we characterize John domains in terms of John domain decomposition property. In addition, we also show that a domain D in ℔n is a John domain if and only if DP is a John domain, where P is a subset of D containing finitely many points of D. The best possibility and an application of the second result are also discussed.
