Partial-dual polynomial as a framed weight system
Qingying Deng, Fengming Dong, Xian'an Jin +1
Recently, Chmutov proved that the partial-dual polynomial considered as a function on chord diagrams satisfies the four-term relations. In this paper, we show that this function on…
Partial-twuality polynomials of delta-matroids
Qi Yan, Xian'an Jin
Gross, Mansour and Tucker introduced the partial-twuality polynomial of a ribbon graph. Chumutov and Vignes-Tourneret posed a problem: it would be interesting to know whether the p…
4-Factor-criticality of vertex-transitive graphs
Wuyang Sun, Heping Zhang
A graph of order is -factor-critical, where is an integer of the same parity as , if the removal of any set of vertices results in a graph with a perfect matching…
Anti-forcing numbers of perfect matchings of graphs
Hongchuan Lei, Yeong-Nan Yeh, Heping Zhang
We define the anti-forcing number of a perfect matching of a graph as the minimal number of edges of whose deletion results in a subgraph with a unique perfect matching…
