On the strength of no normal precipitous filter
نویسندگان
چکیده
We consider a question of T. Jech and K. Prikry that asks if the existence of a precipitous filter implies the existence of a normal precipitous filter. The aim of this paper is to improve a result of [3] and to show that measurable cardinals of a higher order rather than just measurable cardinals are necessary in order to have a model with a precipitous filter but without a normal one.

Precipitous Towers of Normal Filters
We prove that every tower of normal filters of height δ (δ supercompact) is precipitous assuming that each normal filter in the tower is the club filter restricted to a stationary set. We give an example to show that this assumption is necessary. We also prove that every normal filter can be generically extended to a well-founded V -ultrafilter (assuming large cardinals). In this paper we inves...
متن کاملOn almost precipitous ideals
With less than 0# two generic extensions of L are identified: one in which א1, and the other א2, is almost precipitous. This improves the consistency strength upper bound of almost precipitousness obtained in [6], and answers some questions raised there. Also, main results of [5] are generalizedassumptions on precipitousness are replaced by those on ∞-semi precipitousness. As an application it ...
متن کاملA model with a precipitous ideal , but no normal precipitous ideal
Starting with a measurable cardinal κ of the Mitchell order κ++ we construct a model with a precipitous ideal on א1 but without normal precipitous ideals. This answers a question by T. Jech and K. Prikry. In the constructed model there are no Q–point precipitous filters on א1, i.e. those isomorphic to extensions of Cubא1 .
متن کاملEvaluation of the Effect of Sodium Hypochlorite Irrigant on Pull-out Bond Strength of FRC Posts Using Different Resin Cements
Introduction: To evaluate the effects of using sodium hypochlorite irrigant on pull-out bond strength of self-etch and self-adhesive resin cements to dentin. Methods: Sixty intact premolars were decoronated and the root canals were prepared by step-back technique. The teeth were divided into two groups according to the irrigant used during root canal treatment: 5.25% sodium hypochlorite and nor...
متن کاملEffect of induction medium on embryogenesis of maize anther culture and increase of normal haploid plantlet regeneration with wathman filter paper. Seyedeh Zahra Hosseini1*, Payam Pour Mohammadi2 and Garshsb Rigi Cheshmeali1
This study involves in vitro androgenesis of Zea mays L. via anther culture. In the first experiment, three embryo induction media were tested in ETH-M82 genotype of maize. The results showed that the embryo structures were established 2 to 3 weeks after culturing the anthers. The effect of induction medium was significant for embryo frequencies. The obtained results confirm that the induction...
