### Clubs on quasi measurable cardinals

by Kumar and Shelah. [KmSh:1063]

Math Logic Quarterly, 2018

We construct a model satisfying kappa < 2^{aleph_0}
+ club_{kappa} + kappa is quasi measurable. Here, we call kappaquasi measurable if there is an aleph_1-saturated kappa-additive
ideal {I} over kappa . We also show that, in this model, forcing
with {P}(kappa) slash {I} adds one but not
kappa Cohen reals. We introduce a weak club principle and use
it to show that, consistently, for some aleph_{{1}}-saturated
kappa-additive ideal {I} over kappa, forcing with
P(kappa) slash I adds one but not kappa random reals.
