Extremal graphs for vertex-degree-based invariants with given degree sequences

Muhuo Liu, Kexiang Xu, Xiao-Dong Zhang

For a symmetric bivariable function $f (x, y)$ , let the {\it connectivity function} of a connected graph $G$ be $M_{f} (G) = \sum_{uv \in E (G)} f (d (u), d (v))$ , where $d (u)$ is the degree of…

Unified spectral hamiltonian results of balanced bipartite graphs and complementary graphs

Muhuo Liu, Yang Wu, Hong-Jian Lai

There have been researches on sufficient spectral conditions for Hamiltonian properties and path-coverable properties of graphs. Utilizing the Bondy-Chvátal closure, we provide a u…
