Vulnerability Measures and Zagreb Indices of Graphs
Sanju Vaidya, Cheng Chang
This paper establishes sharp bounds for the vulnerability measures of closeness and generalized closeness in graphs and identifies graphs that attain these bounds. It further devel…
Hosoya Polynomials of Mycielskian Graphs
Sanju Vaidya, Aihua Li
Vulnerability measures and topological indices are crucial in solving various problems such as the stability of the communication networks and development of mathematical models fo…
Sharp Bounds for Neighborhood degree based indices of Graphs
Sanju Vaidya, Jeff Chang
In this paper, we will construct formulas and bounds for Neighborhood Degree-based indices of graphs and describe graphs that attain the bounds. Furthermore, we will establish a lo…
Sharp Bounds for Generalized Zagreb Indices of Graphs
Sanju Vaidya, Jeff Chang
In the last forty years, many scientists used graph theory to develop mathematical models for analyzing structures and properties of various chemical compounds. In this paper, we w…
