16:00-16:50 (MS6627) | Will Adkisson (UCLA) | Mutual stationarity and combinatorics at $\aleph_\omega$ | ||
Abstract. Stationary sets are a fundamental concept in set theory, but their definition only makes sense at regular cardinals. We will describe mutual stationarity, a property that can be viewed as an analog of stationarity for singular cardinals, and discuss how it interacts with other combinatorial properties at or near $\aleph_\omega$. In particular, we will discuss the tree property and the failure of the Singular Cardinal Hypothesis. |
