Analytical and computational properties of the variable symmetric division deg index

R. Aguilar-Sanchez, J. A. Mendez-Bermudez, Jose M. Rodriguez +1

The aim of this work is to obtain new inequalities for the variable symmetric division deg index $SD{D}_{\alpha }(G)={\sum }_{uv\in E(G)}(d_u^{\alpha }/d_v^{\alpha }+d_v^{\alpha }/d_u^{\alpha })$, and to characterize grap…
