Title: Some dynamical properties of transcendental meromorphic functions
Abstract: If a transcendental meromorphic function f with finitely many poles has a completely invariant domain U which is simply connected and satisfies some conditions, we prove F(f)=U. And for a transcendental meromorphic function f with the lower order μ<∞ and δ(∞,f)>0, we prove J(f) cannot be contained in any finite set of straight lines completely.
