Wider Thin-Very Tall Superatomic Boolean Algebras

For each regular cardinal k > w we show the consistent existence of a thin very tall superatomic Boolean algebra of width k.Comment: There is a gap in claim 4.

Power function on stationary classes

AbstractWe show that under certain large cardinal requirements there is a generic extension in which the power function behaves differently on different stationary classes. We achieve this by doing an Easton support iteration of the Radin on extenders forcing
