A sequence α\alpha of nonnegative integers is said to be graphic if it is the degree sequence of a simple graph GG, and such a graph GG is called a realization of α\alpha . In this article, we generalize Gale and Ryser’s theorem and give the suff

On the existence of tripartite graphs and n-partite graphs

Autor: Guo, Jiyun, Fu, Miao, Zhang, Yuqin, Li, Haiyan

The degree sequence of a graph is the sequence of the degrees of its vertices. If $\pi$ is a degree sequence of a graph $G$, then $G$ is a realization of $\pi$ and $G$ realizes $\pi$. Determining when a sequence of positive integers is realizable as

Optimal conditions for $(L_1;L_2)$ to be forcibly bigraphic

Autor: Guo, Jiyun, Zhang, Yuqin

Let $L_1=([a_1,b_1],\ldots,[a_m,b_m])$ and $L_2=([c_1,d_1],\ldots,[c_n,d_n]$) be two sequences of intervals consisting of nonnegative integers with $b_1\ge \cdots\ge b_m$ and $d_1\ge \cdots\ge d_n$. In this paper, we first give two optimal conditions
