Median eigenvalues of bipartite graphs
Bojan Mohar, Behruz Tayfeh-Rezaie
For a graph of order and with eigenvalues , the HL-index is defined as $R(G) ={\max}\left\{|λ_{\lfloor(n+1)/2\rfloor}|, |λ_{\lceil(n+…
Median eigenvalues of bipartite subcubic graphs
Bojan Mohar
It is proved that the median eigenvalues of every connected bipartite graph of maximum degree at most three belong to the interval with a single exception of the Heawo…
Large regular bipartite graphs with median eigenvalue 1
Krystal Guo, Bojan Mohar
A recent result of one of the authors says that every connected subcubic bipartite graph that is not isomorphic to the Heawood graph has at least one, and in fact a positive propor…
Integral Cayley graphs and groups
Azhvan Ahmady, Jason P. Bell, Bojan Mohar
We solve two open problems regarding the classification of certain classes of Cayley graphs with integer eigenvalues. We first classify all finite groups that have a "non-trivial"…
