Some pathological examples of precipitous ideals
We construct a model with an indecisive precipitous ideal and a model with a precipitous ideal with a non precipitous normal ideal below it. Such kind of examples were previously ...

On Partially Wellfounded Generic Ultrapowers
We construct a model without precipitous ideals but so that for each < 3 there is a normal ideal over 1 with generic ultrapower wellfounded up to the image of .
