Results on resistance distance and Kirchhoff index of graphs with generalized pockets
Qun Liu
In this paper, we derive closed-form formulas for resistance distance and Kirchhoff index of graphs with generalized pockets in terms of the resistance distance and Kirchhoff index…

Resistance distance and Kirchhoff index in generalized R-vertex and R-edge corona for graphs
Qun Liu
For a graph G, the graph R(G) of a graph G is the graph obtained by adding a new vertex for each edge of G and joining each new vertex to both end vertices of the correspond- ing e…

Normalized Laplacian spectrum of some generalized subdivision-corona of two regular graphs
Qun Liu, Zhongzhi Zhang
In this paper, we determine the two normalized Laplacian spectrum of generalized subdivision- vertex corona, subdivision-edge corona for a connected regular graph with an arbitrary…
