Abstract :
In this paper, we give some necessary conditions for a complex difference equation of Malmquist type ∑j=1nf(z+cj)=P(f(z))Q(f(z)), where n(∈N)≥2, and P(f(z)) and Q(f(z)) are relatively prime polynomials in f(z) with small functions as coefficients, admitting a meromorphic function of finite order. Moreover, the properties of finite order transcendental meromorphic solutions for complex difference equation ∏nj=1f(z+cj)=P(f(z))/Q(f(z)) are also investigated.
