摘要: 对于给定的棱数 ,提供可定向、不可定向以及全体一般根地图的计数方程 .虽然它们都是 Riccati型的微分方程 ,给出了确定它们解的简单递推公式 .从而 ,相应的计数函数可以被提取Abstract: Provide the equations satisfied by the enumerating functions of orientable,nonorientable and total general rooted maps.Although they are all in Riccati type,their solutions are determined by recursions and then the enumerating functions of them with the size as the parameter can be simply evaluated.
