Abstract : this paper provides the functional equation of general rooted maps with the number of inner faces , the rooted face valency and the number of non - rooted vertices as parameters on the torus , and gives an explicit expression of the enumerating function of these maps with the number of inner faces and of non - rooted vertices , then the number of these maps with the size as a parameter whose asymptotic result had been obtained in [ 2 ] is obtained as a corollary 文摘:這篇文章給出了環(huán)面上以內(nèi)面?zhèn)€數(shù),根面次和非根節(jié)點(diǎn)個(gè)數(shù)為參數(shù)的一般有根地圖的計(jì)數(shù)方程,導(dǎo)出了以內(nèi)面?zhèn)€數(shù)和非根節(jié)點(diǎn)個(gè)數(shù)為參數(shù)的這類地圖的計(jì)數(shù)方程的精確解.作為推論,推出了以邊數(shù)為參數(shù)的這類地圖的個(gè)數(shù),其近似解在文獻(xiàn)[ 2 ]中已討論
