Maximum values of degree-based entropies of bipartite graphs

作者:

Highlights:

• Determine the maximum value of the degree-based entropy among bipartite graphs with a given number of vertices and edges.

• Characterize all the extremal graphs by the corresponding degree sequences.

• The main result implies the known result due to Cao et al. (2014) that the degree-based entropy of the path attains the maximum value among all trees with a given number of vertices.
