Northeastern Mathematical Journal 2004年 第3期20卷 265-270页
作者: 郝荣霞 蔡俊亮 Department of Mathematics Beijing Jiaotong University Beijing 100044 Department of Mathematics Beijing Normal University Beijing 100875he number of rooted nearly 2-regular maps with the valency of root-vertex the number of non-rooted vertices and the valency of root-face as three parameters is obtained. Furthermore the explicit expressions of the special cases including loopless nearly 2-regular maps and simple nearly 2-regular maps in terms of the above three parameters are derived.
