Equidistributed statistics on Fishburn matrices and permutations
Dandan Chen, Sherry H. F. Yan, Robin D. P. Zhou
Recently, Jelínek conjectured that there exists a bijection between certain restricted permutations and Fishburn matrices such that the bijection verifies the equidistribution of s…
Strong Subgraph Connectivity of Digraphs: A Survey
Yuefang Sun, Gregory Gutin
In this survey we overview known results on the strong subgraph -connectivity and strong subgraph -arc-connectivity of digraphs. After an introductory section, the paper is d…
Proving a conjecture on chromatic polynomials by counting the number of acyclic orientations
Fengming Dong, Jun Ge, Helin Gong +3
The chromatic polynomial of a graph of order can be expressed as , where is interpreted as the number of broken-cycle…
Strong Subgraph -connectivity
Yuefang Sun, Gregory Gutin, Anders Yeo +1
Generalized connectivity introduced by Hager (1985) has been studied extensively in undirected graphs and become an established area in undirected graph theory. For connectivity pr…
