Meromorphic Solutions of a Differential Equation with Polynomial Coefficients

Meromorphic Solutions of a Differential Equation with Polynomial Coefficients We give new estimates for the maximum number M of distinct meromorphic solutions and also for the maximum number L of linearly independent meromorphic solutions of the first order differential equation $$f^\prime = p_0+p_1f+...+p_nf^n,\ \ \ n\geq 3,$$ where each P k is a polynomial and P n ≢ 0. The estimate for M depends only on n and the number d of distinct zeros of P n, while the estimate for L depends only on d. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Computational Methods and Function Theory Springer Journals

Abstract

We give new estimates for the maximum number M of distinct meromorphic solutions and also for the maximum number L of linearly independent meromorphic solutions of the first order differential equation $$f^\prime = p_0+p_1f+...+p_nf^n,\ \ \ n\geq 3,$$ where each P k is a polynomial and P n ≢ 0. The estimate for M depends only on n and the number d of distinct zeros of P n, while the estimate for L depends only on d.
