标题： Extensions of the Erdős-Rado Theorem

摘要： 我们建立了Erdos-Rado定理的各种扩展，特别是涉及序数的情况，并且总是涉及普通的分划关系。 大部分结果可以被视为适当解释的分支原理的结论。 其中一些问题已经悬而未决很长时间。 论文开头有详细的总结。 该论文计划作为1991年班夫会议论文集的一部分发表。 显示英文摘要

摘要： We establish a variety of extensions to the Erdos-Rado Theorem, particularly involving ordinal numbers, and always involving ordinary partition relations. Most of the results can be regarded as consequences of the Ramification Principle, interpreted appropriately. Some of these problems have been open for a long time. There is a detailed summary at the beginning of the paper. The paper is scheduled to appear as part of the proceedings of the Banff meeting held in 1991.
