Together this continues older research by erdős, galvin, hajnal, larson and takahashi and more recent investigations by abraham, bonnet, cummings, džamonja, komjáth, shelah and thompson. The present paper gives an account of investigations into generalisations of scattered linear orders and their partition relations for both singletons and pairs Polarised partition relations are also considered, and the results are used to answer several problems posed by garti, larson and shelah.

The consistency of the positive partition relation $\mathfrak {b} \rightarrow { (\mathfrak {b}, \alpha)}^ {2}$ for all $\alpha < {\omega}_ {1}$ for the bounding number $\mathfrak {b}$ is also established from large cardinals.
We prove that for every inaccessible cardinal $κ$, if $κ$ admits a stationary set that does not reflect at inaccessibles, then the classical negative partition.
Abstract page for arxiv paper 0902.0440v1 Many partition relations below density The partition calculus was introduced over six decades ago by erdős and rado in their seminal paper [er56] They introduced the ordinary partition relation which concern partitions of finite subsets of a set of a given size and the polarised partition relation which concerns partitions of finite subsets of products of sets of a given size
The notion of “size” here was mostly taken to. In 1956, 48 years after hausdorff provided a comprehensive account on ordered sets and defined the notion of a scattered order, erdős and rado founded the partition calculus in a seminal paper
