요약 | This thesis divides naturally into two parts, each concerned with the extent to which the theory of L(R) can be changed by forcing. |
요약 | The first part focuses primarily on applying generic-absoluteness principles to show that definable sets of reals enjoy regularity properties. We begin, in the spirit of Mathias, by establishing a strong Ramsey property for sets of reals in the |
요약 | In Chapter 3 we stray from the main line of inquiry to briefly study a game-theoretic characterization of filters with the Baire Property. |
요약 | Neeman and Zapletal showed, assuming roughly the existence of a proper class of Woodin cardinals, that the boldface theory of L( R) cannot be changed by proper forcing. They call their result the Embedding Theorem, because they conclude that in |
요약 | Part I concludes with Chapter 5, a short list of open questions. |
요약 | In the second part of the thesis, we conduct a finer analysis of the Embedding Theorem and its consistency strength. Schindler found that the the Embedding Theorem is consistent relative to much weaker assumptions than the existence of Woodin ca |
요약 | The proof of Theorem 6.2 splits naturally into two arguments. In Chapter 7 we extend Kunen's method of coding reals into a specializing function to allow for trees with uncountable levels that may not belong to L. This culminates in Theorem 7.4 |
요약 | We complete the argument in Chapter 8, where we show that if the Tree Reflection Principle holds in every alpha-closed extension, then "special character omitted is remarkable in L. |
요약 | In Chapter 9 we review Schindler's proof of generic absoluteness from a remarkable cardinal to show that the argument gives a level-by-level upper bound. |
요약 | Chapter 10 is devoted to partially reversing the level-by-level upper bound of Chapter 9. We are able to show that L(R)-absoluteness for lambda-linked posets implies that the interval [kappa V1 ,lambda] is Sigma21-remarkable in L. |
