有限群的子群图的亏格

The genus of the subgroup graph of a finite group

Andrea Lucchini

摘要:

对一个有限群$G$,用$γ(L(G))$表示$G.$的子群图的亏格.证明了当$G$的秩或$|G|$的素除子数趋于无穷大时,$γ(L(G))$趋于无穷大.

英文摘要:

For a finite group $G$ denote by $γ(L(G))$ the genus of the subgroup graph of $G.$ We prove that $γ(L(G))$ tends to infinity as either the rank of $G$ or the number of prime divisors of $|G|$ tends to infinity.
