在这篇论文中,我们研究了下面的Riccati微分方程w'=Q(z)(a+bw+cw^2),这里Q(名)是有理函数.我们得到了上面的微分方程具有亚纯解的充分必要条件,并得到了所有的精确解
In this paper, we study the special Riccati differential equation w'=Q(z)(a+bw+cw^2),where Q(z) is a rational function. We get the necessary and sufficient conditions of the above equation admitting meromorphic solutions and find its exact meromorphic solutions.
