چکیده
This paper designs a set of graph operations and proves that starting from Gd , by repeatedly applying these operations, one can construct all graphs G with χc(G) ≥ k/d (for k/d ≥ 3). This can be viewed as an analogue of Hajós’ Theorem for the circular chromatic number.

An Analogue of Hajós' Theorem for the Circular Chromatic Number (II)
This paper designs a set of graph operations and proves that starting from Gd , by repeatedly applying these operations, one can construct all graphs G with χc(G) ≥ k/d (for k/d ≥ 3). This can be viewed as an analogue of Hajós’ Theorem for the circular chromatic number.
متن کاملA short construction of highly chromatic digraphs without short cycles
A natural digraph analogue of the graph-theoretic concept of an ‘independent set’ is that of an ‘acyclic set’, namely a set of vertices not spanning a directed cycle. Hence a digraph analogue of a graph coloring is a decomposition of the vertex set into acyclic sets. In the spirit of a famous theorem of P. Erdős [Graph theory and probability, Canad. J. Math. 11 (1959), 34–38], it was shown prob...

In 2015, Alishahi and Hajiabolhassan introduced the altermatic number of graphs as a lower bound for the chromatic number of them. Their proof is based on the Tucker lemma, a combinatorial counterpart of the Borsuk-Ulam theorem, which is a well-known result in topological combinatorics. In this paper, we present a combinatorial proof for the Alishahi-Hajiabolhassan theorem.

The local chromatic number of a graph was introduced in [12]. It is in between the chromatic and fractional chromatic numbers. This motivates the study of the local chromatic number of graphs for which these quantities are far apart. Such graphs include Kneser graphs, their vertex color-critical subgraphs, the Schrijver (or stable Kneser) graphs; Mycielski graphs, and their generalizations; and...
