In this paper, we consider the family of generalized Petersen graphs P（n,4）. We prove that the metric dimension of P（n, 4） is 3 when n = 0 （mod 4）, and is 4 when n = 4k ＋ 3 （k is even）.For n = 1,2 （mod 4） a...In this paper, we consider the family of generalized Petersen graphs P（n,4）. We prove that the metric dimension of P（n, 4） is 3 when n = 0 （mod 4）, and is 4 when n = 4k ＋ 3 （k is even）.For n = 1,2 （mod 4） and n = 4k ＋ 3 （k is odd）, we prove that the metric dimension of P（n,4） is bounded above by 4. This shows that each graph of the family of generalized Petersen graphs P（n, 4） has constant metric dimension.展开更多

In this paper, the structures of embeddings of circulant graph C（2n ＋ 1; {1, n}） on the projective plane are described, the number of embeddings of C（2n ＋ 1; {1, n}） on the projective plane follows, then the number of embeddings of the generalized Petersen graph P（2n ＋ 1, n） on the projective plane is deduced from that of C（2n ＋ 1; {1, n}）, because C（2n ＋ 1; {1, n}） is a minor of P（2n ＋ 1, n）, their structures of embeddings have relations. In the same way, the number of embeddings of the generalized Petersen graph P（2n, 2） on the projective plane is also obtained.展开更多
The generalized Petersen graphs p(n,k) n≥3, 1≤k<n/2, consist of an outer n-cycle x0x1 x2'''xn--1 , a set of n spokes x,yi (O≤i≤n--1), and n inner edges yiyi+k with indices taken modulo n.This paper ...The generalized Petersen graphs p(n,k) n≥3, 1≤k<n/2, consist of an outer n-cycle x0x1 x2'''xn--1 , a set of n spokes x,yi (O≤i≤n--1), and n inner edges yiyi+k with indices taken modulo n.This paper deals with (a,b)-consecutive labelings of generalized Petersen graph p(n,k).展开更多
