摘要 研究了一类非线性差分方程f^n(z)+b_(n-1)(z)f^(n-1)(z)+…+b_2(z)f^2(z)+L(z,f)=h(z),其中,b_2(z),…,b_(n-1)(z)为多项式,L(z,f)为f(z)的线性差分多项式,得到了这类方程亚纯解的存在性、增长性和值分布的一些结果. A certain type of nonlinear difference equations of the form f^n(z) +bn-1(z) f^n-1(z) +…+b2(z) f^2(z) +L(z,f) = h(z) is studied,where b2(z),…,b(n-1)(z) are polynomials and L(z,f) is a linear difference polynomial of f(z). Some results on existence,growth and value distribution of meromorphic solutions to these equations are obtained.
