Abstract

In this article, we consider the non-linear difference equation
(f(z + 1)f(z)-1)(f(z)f(z-1)-1)=P(z, f(z))/Q(z, f(z)),
where P(z, f(z)) and Q(z, f(z)) are relatively prime polynomials in f(z) with rational coefficients. For the above equation, the order of growth, the exponents of convergence of zeros and poles of its transcendental meromorphic solution f(z), and the exponents of convergence of poles of difference △f(z) and divided difference △f(z)/f(z) are estimated. Furthermore, we study the forms of rational solutions of the above equation.
