چکیده

We give an elementary proof of the fact that regressive Ramsey numbers are Ackermannian. This fact was first proved by Kanamori and McAloon with mathematical logic techniques. Nous vivons encore sous le règne de la logique, voilà, bien entendu, à quoi je voulais en venir. Mais les procédés logiques, de nos jours, ne s’appliquent plus qu’à la résolution de problèmes d’intérêt secondaire. [1, 1924, p. 13]

Classifying the phase transition threshold for unordered regressive Ramsey numbers

Following ideas of Richer (2000) we introduce the notion of unordered regressive Ramsey numbers or unordered Kanamori-McAloon numbers. We show that these are of Ackermannian growth rate. For a given number-theoretic function f we consider unordered f -regressive Ramsey numbers and classify exactly the threshold for f which gives rise to the Ackermannian growth rate of the induced unordered f -r...

Sharp thresholds for the phase transition between primitive recursive and Ackermannian Ramsey numbers

We compute the sharp thresholds on g at which g-large and g-regressive Ramsey numbers cease to be primitive recursive and become Ackermannian. We also identify the threshold below which g-regressive colorings have usual Ramsey numbers, that is, admit homogeneous, rather than just min-homogeneous sets.

The Threshold for Ackermannian Ramsey Numbers

For a function g : N → N, the g-regressive Ramsey number of k is the least N so that N min −→ (k)g. This symbol means: for every c : [N ] → N that satisfies c(m, n) ≤ g(min{m, n}) there is a min-homogeneous H ⊆ N of size k, that is, the color c(m, n) of a pair {m, n} ⊆ H depends only on min{m, n}. It is known ([4, 5]) that Id-regressive Ramsey numbers grow in k as fast as Ack(k), Ackermann’s fu...

Regressive functions on pairs

We compute an explicit upper bound for the regressive Ramsey numbers by a combinatorial argument, the corresponding function being of Ackermannian growth. For this, we look at the more general problem of bounding g(n,m), the least l such that any regressive function f : [m, l] → N admits a min-homogeneous set of size n. Analysis of this function also leads to the simplest known proof that the r...

Sharp thresholds for hypergraph regressive Ramsey numbers

The f -regressive Ramsey number R f (d, n) is the minimum N such that every colouring of the d-tuples of an N -element set mapping each x1, . . . , xd to a colour ≤ f(x1) contains a min-homogeneous set of size n, where a set is called min-homogeneous if every two d-tuples from this set that have the same smallest element get the same colour. If f is the identity, then we are dealing with the st...
