چکیده
The List Hadwiger Conjecture asserts that every Kt-minor-free graph is tchoosable. We disprove this conjecture by constructing a K3t+2-minor-free graph that is not 4t-choosable for every integer t ≥ 1.

متن کاملContractibility and the Hadwiger Conjecture
Consider the following relaxation of the Hadwiger Conjecture: For each t there exists Nt such that every graph with no Kt minor admits a vertex partition into dαt + βe parts, such that each component of the subgraph induced by each part has at most Nt vertices. The Hadwiger Conjecture corresponds to the case α = 1, β = −1 and Nt = 1. Kawarabayashi and Mohar [K. Kawarabayashi, B. Mohar, A relaxe...
متن کاملSphere packings in 3-space
In this paper we survey results on packings of congruent spheres in 3-dimensional spaces of constant curvature. The topics discussed are as follows: Hadwiger numbers of convex bodies and kissing numbers of spheres; Touching numbers of convex bodies; Newton numbers of convex bodies; One-sided Hadwiger and kissing numbers; Contact graphs of finite packings and the combinatorial Kepler problem; Is...
متن کاملDisproof of the Mertens Conjecture
The Mertens conjecture states that M(x) < x ⁄2 for all x > 1, where M(x) = n ≤ x Σ μ(n) , and μ(n) is the Mo bius function. This conjecture has attracted a substantial amount of interest in its almost 100 years of existence because its truth was known to imply the truth of the Riemann hypothesis. This paper disproves the Mertens conjecture by showing that x → ∞ lim sup M(x) x − ⁄2 > 1. 06 ....
متن کاملThomassen's Choosability Argument Revisited
Thomassen (J. Combin. Theory Ser. B, 62 (1994), pp. 180–181) proved that every planar graph is 5-choosable. This result was generalized by Škrekovski (Discrete Math., 190 (1998), pp. 223–226) and He, Miao, and Shen (Discrete Math., 308 (2008), pp. 4024–4026), who proved that every K5-minor-free graph is 5-choosable. Both proofs rely on the characterization of K5-minorfree graphs due to Wagner (...
