Title: Shelah’s singular compactness theorem
Abstract:
Shelah’s singular compactness theorem is a general result showing that a singular cardinal λ has properties reminiscent of those enjoyed by large cardinals: for example
If G is an abelian group of size λ and every subgroup of G with size less than λ is free, then G is free. continue reading…
