Asymptotically Good List-Colorings
1996
Journal of combinatorial theory. Series A
Notice that an ordinary coloring problem in which some colors have already been assigned is a list-coloring problem. ...
(For instance, if G is an odd cycle and the lists are of size 2, then a coloring exists exactly when not all lists are the same.) ...
Note A s cannot come from G v , since under K no edge of G v is permanently colored # j .) ...

List-colorings and the semirandom method again A rough rationale for the good asymptotics of the types of hypergraphs appearing in Theorems 2.1 and 2.2 is that we are in a probability space -namely M(H ...
List-colorings The list-chromatic index, x|(W), of H is the least t such that if S (A) is a set ("list") of size t for each A E H, then there exists a coloring a of H with o~(A) G S(A) for each A G H. ...

Some stability and exact results in generalized Turán problems
[article]

arXiv
pre-print
The K k+1 -Turángood graphs listed in Theorem 2.4 are also F -Turán-good. ...
Now we are ready to list our contributions. Proposition 1.3. Let χ(F ) = k + 1 and H be weakly asymptotically F -Turán-good and weakly K k+1 -Turán-stable. Then H is weakly F -Turán-stable. ...
In the case H is also K k+1 -Turán-good, we have that the Turán graph maximizes the number of copies of H among complete k-partite n-vertex graphs. ...

When Δ≤20 the value of m is close to 1/2Δ, but as Δ increases m becomes asymptotic to about 1/4Δ+5. ...
For a graph G and nonnegative integer k, we say G is a k-list-edge-critical graph if χ'_ℓ(G)>k, but χ'_ℓ(G-e)≤ k for all e ∈ E(G). ...
In this sense, good counts are achieved from knowing the list-edge-colorability of bipartite graphs. ...

In any good coloring, if we can find a vertex of degree 6 where the colors alternate, we can switch the colors and get another good coloring. ...
