The aim of this paper is to show that the minimum Hadwiger number of graphs with average degreek isO(k/√logk). Specially, it follows that Hadwiger’s conjecture is true for almost all graphs withn vertices, furthermore ifk is large enough then for almost all graphs withn vertices andnk edges.

This is a survey of Hadwiger’s conjecture from 1943, that for all t ≥ 0, every graph either can be t-coloured, or has a subgraph that can be contracted to the complete graph on t + 1 vertices. ThisExpand
Minor Extremal Problems Using Turan Graphs
The extremal number ex(n;MKp) denotes the maximum number of edges of a graph of order n not containing a complete graph Kp as a minor. In this paper we find a lower bound for this extremal number
List Colouring Squares of Planar Graphs
It is shown that the chromatic number of the square of every planar graph G with maximum degree Δ ⩾ 8 is at most ⌈ 3 2 Δ ⌉ + 1, and indeed this is true for the list Chromatic number. Expand
Dense Minors In Graphs Of Large Girth
We show that a graph of girth greater than 6 log k+3 and minimum degree at least 3 has a minor of minimum degree greater than k. This is best possible up to a factor of at most 9/4. As a corollary,Expand
Cycles of Given Size in a Dense Graph
It is shown that every graph with average degree at least $\frac{4}{3}kr$ contains $k$ vertex disjoint cycles, each of order at least $r$ as long as $k \geq 6$. Expand
Rank-width and tree-width of H-minor-free graphs
It is proved that for any fixed r>=2, the tree-width of graphs not containing K"r as a topological minor is bounded by a linear function of their rank-width. Expand
Disproof of the List Hadwiger Conjecture
The List Hadwiger Conjecture is disproved by constructing a-minor-free graph that is not $4t-choosable for every integer $t\geq 1$. Expand
Minors in graphs of large girth
The case g = 5 of the result implies Hadwiger's conjecture for C4-free graphs of sufficiently large chromatic number and a well-known conjecture about the minimal order of graphs of given minimum degree and large girth is implied. Expand
Complete minors in digraphs with given dichromatic number
The dichromatic number ~ χ(D) of a digraph D is the smallest k for which it admits a k-coloring where every color class induces an acyclic subgraph. Inspired by Hadwiger’s conjecture for undirectedExpand

This work shows how to explicitly construct dense graphs for which the size of the largest clique minor is sublinear in the number of vertices using blow-ups of small graphs with this property, which leads to the study of a fractional variant of the cliqueMinor number. Expand

An elementary proof is given of a theorem of Ore about this invariant about the maximum order of a connected graph onto which G is contractible and the extremal problem of finding the maximum Z(G) over all graphs G of a given order and regularity degree is solved. Expand
Probabilistic Methods in Combinatorics
In 1947 Paul Erdős [8] began what is now called the probabilistic method. He showed that if \(\left( {\begin{array}{*{20}{c}} n \\ k \\ \end{array} } \right){{2}^{{1 - \left( {\begin{array}{*{20}{c}}Expand
