The average genus for bouquets of circles and dipoles
Jinlian Zhang, Xuhui Peng, Yichao Chen
The bouquet of circles and dipole graph are two important classes of graphs in topological graph theory. For , we give an explicit formula for the average genu…

Limits for embedding distributions
Jinlian Zhang, Xuhui Peng, Yichao Chen
In this paper, we find and prove that, under some conditions, the embedding distributions of -linear graph families with spiders are asymptotic normal distributions. It can been…

Euler-genus distributions of cubic Halin graphs
Jinlian Zhang, Xuhui Peng
Gross derived an -time algorithm to calculate the genus distribution of a given cubic Halin graph. In this paper, with the help of overlap matrix, we get a recurrence relat…
