Abstract
Using Koszmider's strongly unbounded functions, we show the following consistency result: Suppose that are infinite cardinals such that , and , and is an ordinal with and . Then, in some cardinal-preserving generic extension there is a superatomic Boolean algebra such that - , - the cardinality of the th level of is for every , - and the cardinality of the th level of is Especially, and can be cardinal sequences of superatomic Boolean algebras.
