%0 Journal Article %T On Potentially $(K_5-H)$-graphic Sequences %A Lili Hu %A Chunhui Lai %A Ping Wang %J Mathematics %D 2007 %I arXiv %X Let $K_m-H$ be the graph obtained from $K_m$ by removing the edges set $E(H)$ of $H$ where $H$ is a subgraph of $K_m$. In this paper, we characterize the potentially $K_5-P_4$ and $K_5-Y_4$-graphic sequences where $Y_4$ is a tree on 5 vertices and 3 leaves. %U http://arxiv.org/abs/math/0702166v1
