In this paper, we study the uniqueness problems on meromorphic functions concerning di¤erential polynomials, and obtain two theorems which generalize and improve some known results. 1 Introduction In this paper, a meromorphic function means meromorphic in the open complex plane. We shall adopt the standard notations in Nevanlinna’s value distribution theory(More)
In this paper, we consider the differential equation F ′ −Q1 = Re (F −Q2), where Q1 and Q2 are polynomials with Q1Q2 6≡ 0, R is a rational function and α is an entire function. We consider solutions of the form F = f, where f is an entire function and n ≥ 2 is an integer, and we prove that if f is a transcendental entire function, then Q1 Q2 is a polynomial(More)
