On the sum and spread of reciprocal distance laplacian eigenvalues of graphs in terms of harary index

HIGHLIGHTS

• who: S. Khan et al. from the Department of Mathematics, University of Kashmir, Srinagar, India have published the article: On the Sum and Spread of Reciprocal Distance Laplacian Eigenvalues of Graphs in Terms of Harary Index, in the Journal: Symmetry 2022, 14, 1937. of /2022/
• what: The authors determine the extremal cases corresponding to these bounds. The authors show that equality holds for Kn.

SUMMARY

For each 1 ≤ i and amp;lt; j ≤ n, the authors have dij ≥ 1 so that ∑ 1≤ i and amp;lt; j ≤ n 1 ≤ ∑ 1=d2ij . . .
