On the first and second eigenvalue of finite and infinite uniform hypergraphs
Hong-Hai Li, Bojan Mohar
Lower bounds for the first and the second eigenvalue of uniform hypergraphs which are regular and linear are obtained. One of these bounds is a generalization of the Alon-Boppana T…
Almost All Regular Graphs are Normal
Seyed Saeed Changiz Rezaei, Seyyed Aliasghar Hosseini, Bojan Mohar
In 1999, De Simone and Körner conjectured that every graph without induced contains a clique cover and a stable set cover such th…
Dichromatic number and fractional chromatic number
Bojan Mohar, Hehui Wu
The dichromatic number of a graph is the maximum integer such that there exists an orientation of the edges of such that for every partition of the vertices into fewer…
Bishellable drawings of
Bernardo M. Ábrego, Oswin Aichholzer, Silvia Fernández-Merchant +6
The Harary--Hill conjecture, still open after more than 50 years, asserts that the crossing number of the complete graph is $ H(n) = \frac 1 4 \left\lfloor\frac{\mathstrut n}…
The Genus Distribution of Doubly Hexagonal Chains
Bojan Mohar
By using the Transfer Matrix Method, explicit formulas for the embedding distribution of doubly hexagonal chain graphs are computed.
Hermitian adjacency spectrum and switching equivalence of mixed graphs
Bojan Mohar
It is shown that an undirected graph is cospectral with the Hermitian adjacency matrix of a mixed graph obtained from a subgraph of by orienting some of its edges i…
Hermitian adjacency matrix of digraphs and mixed graphs
Krystal Guo, Bojan Mohar
The paper gives a thorough introduction to spectra of digraphs via its Hermitian adjacency matrix. This matrix is indexed by the vertices of the digraph, and the entry correspondin…
