Graphical virtual links and a polynomial of signed cyclic graphs
Qingying Deng, Xian'an Jin, Louis H Kauffman
For a signed cyclic graph G, we can construct a unique virtual link L by taking the medial construction and convert 4-valent vertices of the medial graph to crossings according to…
The Minimal Coloring Number Of Any Non-splittable -colorable Link Is Four
Meiqiao Zhang, Xian'an Jin, Qingying Deng
K. Ichihara and E. Matsudo introduced the notions of -colorable links and the minimal coloring number for -colorable links, which is one of invariants for l…
Characterizations of Eulerian and even-face partial duals of ribbon graphs
Qingying Deng, Xian'an Jin
Huggett and Moffatt characterized all bipartite partial duals of a plane graph in terms of all-crossing directions of its medial graph. Then Metsidik and Jin characterized all Eule…
Several extreme coefficients of the Tutte polynomial of graphs
Helin Gong, Mengchen Li, Xian'an Jin
Let be the coefficient of in the Tutte polynomial of a connected bridgeless and loopless graph with order and size . It is trivial that $t_…
