[Page generation failure. The bibliography processor requires a browser with Javascript enabled.] We call E subset-of-or-is-equal-to {0,1}kappa projective if for some countable A subset-of-or-is-equal-to kappa there is an E(A) subset-of-or-is-equal-to {0,1}A such that E = E(A) x {0,1}kappa/A and E(A) is a projective subset of the Cantor set {0,1}A. We construct a model where Haar measure on {0,1... |

[Page generation failure. The bibliography processor requires a browser with Javascript enabled.] We study sets on which measurable real-valued functions on a measurable space with negligibles are determined by their range. |

[Page generation failure. The bibliography processor requires a browser with Javascript enabled.] This is a survey paper giving a self-contained account of Shelah's theory of the pcf function pcf(a) = {cf(PI a/D, < D): D is an ultrafilter on a}, where a is a set of regular cardinals such that \a\ < min(a). We also give several applications of the theory to cardinal arithmetic, the exi... |

[Page generation failure. The bibliography processor requires a browser with Javascript enabled.] The current state of knowledge concerning liftings for noncomplete probability spaces is discussed. This is a somewhat expanded version of the author's talk given at the 1991 Summer Conference on General Topology and Applications in Honor of Mary Ellen Rudin and Her Work. |

[Page generation failure. The bibliography processor requires a browser with Javascript enabled.] We investigate the cofinality of the partial order N-kappa of functions from a regular cardinal kappa into the ideal N of Lebesgue measure zero subsets of R. We show that when add(N) = kappa and the covering lemma holds with respect to an inner model of GCH, then cf(N-kappa) = max{cf(kappa(kappa)), ... |

[Page generation failure. The bibliography processor requires a browser with Javascript enabled.] We prove that it is relatively consistent with ZFC that in any perfect Polish space, for every nonmeager set A there exists a nowhere dense Cantor set C such that A boolean AND C is nonmeager in C. We also examine variants of this result and establish a measure theoretic analog. |
