Abstract

We give bounds for {Mathematical expression} where cf δ=א1, (∀a<δ) {Mathematical expression}, in cases which previously remained opened, including the first such cardinal: the ω 1-th cardinal in C ω=∩n<ω C n where C 0 is the cardinal and C n+1 the set of fixed points of C n. No knowledge of earlier results is required. A subsequent work generalizing this was applied to many more cardinals ([Sh 7]).
