Abstract

Abstract

En 中文
Assuming four strongly compact cardinals, it is consistent that all entries in Cichon's diagram (apart from add(M) and cof(M), whose values are determined by the others) are pairwise different; more specifically, aleph(1) < add(N) < cov(N) < b < non(M) < cov(M) < partial derivative < non(N) < cof(N) < 2(aleph 0).
