A Survey on Hedetniemi’s Conjecture
نویسنده
چکیده
More than 30 years ago, Hedetniemi made a conjecture which says that the categorical product of two n-chromatic graphs is still n-chromatic. The conjecture is still open, despite many different approaches from different point of views. This article surveys methods and partial results; and discuss problems related to or motivated by this conjecture.

[gtn Liv:6] Hedetniemi’s Conjecture, 40 Years Later
Hedetniemi’s conjecture states that the chromatic number of a categorical product of graphs is equal to the minimum of the chromatic numbers of the factors. We survey the many partial results surrounding this conjecture, to review the evidence and the counter evidence.
متن کاملHedetniemi’s Conjecture Via Alternating Chromatic Number
In an earlier paper, the present authors (2013) [1] introduced the alternating chromatic number for hypergraphs and used Tucker’s Lemma, an equivalent combinatorial version of the Borsuk-Ulam Theorem, to show that the alternating chromatic number is a lower bound for the chromatic number. In this paper, we determine the chromatic number of some families of graphs by specifying their alternating...
متن کاملHedetniemi's Conjecture and the Retracts of a Product of Graphs
We show that every core graph with a primitive automorphism group has the property that whenever it is a retract of a product of connected graphs, it is a retract of a factor. The example of Kneser graphs shows that the hypothesis that the factors are connected is essential. In the case of complete graphs, our result has already been shown in [4, 17], and it is an instance where Hedetniemi’s co...
متن کاملHedetniemi’s conjecture and fiber products of graphs
We prove that for n ≥ 4, a fiber product of n-chromatic graphs over n-colourings can have chromatic number strictly less than n. This refutes a conjecture of Y. Carbonneaux, S. Gravier, A. Khelladi, A. Semri, Coloring fiber product of graphs. AKCE Int. J. Graphs Comb. 3 (2006), 59–64.
متن کاملOn the algorithmic aspects of Hedetniemi’s conjecture
We present a polynomial algorithm, implicit in the work of ElZahar and Sauer, which inputs a 3-colouring of a categorical product of two graphs and outputs a 3-colouring of one of the factors. We raise a question about the existence of polynomial algorithms for colouring the vertices of some graphs in terms of intrinsic succint description of the vertices rather than in terms of the (exponentia...
