Applications of the topological representation of the pcf-structure (Q938245)

For details regarding PCF theory, reference may be made to \textit{S. Shelah}'s papers of the 1980's or his book [Cardinal arithmetic. Oxford: Clarendon Press (1994; Zbl 0848.03025)]. From the abstract: ``In this paper, the author considers simplified representation theorems in pcf-theory, and in particular he proves that if \(\aleph_\omega^{\aleph_0} > \aleph_{\omega_1}\cdot 2^{\aleph_0}\) then there are cofinally many sequences of regular cardinals such that \(\aleph_{\omega_1+1}\) is represented by these sequences modulo the ideal of finite subsets, using a topological approach to the pcf-structure.''
