چکیده
We prove various results on the notion of ordinal ultrafiters introduced by J. Baumgartner. In particular, we show that this notion of ultrafilter complexity is independent of the more familiar Rudin-Keisler ordering.

متن کاملA Few Special Ordinal Ultrafilters
We prove various results on the notion of ordinal ultraaters introduced by J. Baumgartner. In particular, we show that this notion of ultraalter complexity is independent of the more familiar Rudin-Keisler ordering. 1. Introduction Interesting ultraalters are those comprising rich combinatorial properties of some sort. Traditional criterions consist of partition relations on the natural numbers...
متن کاملRamsey-like cardinals II
This paper continues the study of the Ramsey-like large cardinals introduced in [Git09] and [WS08]. Ramsey-like cardinals are defined by generalizing the “existence of elementary embeddings” characterization of Ramsey cardinals. A cardinal κ is Ramsey if and only if every subset of κ can be put into a κ-size transitive model of ZFC for which there exists a weakly amenable countably complete ult...
متن کاملSome constructions of ultrafilters over a measurable cardinal
Some non-normal κ−complete ultrafilters over a measurable κ with special properties are constructed. Questions by A. Kanamori [4] about infinite Rudin-Frolik sequences, discreteness and products are answered.
متن کاملNew phase II control chart for monitoring ordinal contingency table based processes
In some statistical process monitoring applications, quality of a process or product is described by more than one ordinal factors called ordinal multivariate process. To show the relationship between these factors, an ordinal contingency table is used and modeled with ordinal log-linear model. In this paper, a new control charts based on ordinal-normal statistic is developed to monitor the ord...
