https://doi.org/10.1007/978-3-540-44778-8We present model–theoretic techniques to obtain conservation results for first order bounded arithmetic theories, based on a hierarchical version of the well known notion of an existentially closed model.

-Trivial Closed Sets and Continuous Functions,We investigate the notion of .-triviality for closed sets and continuous functions. Every .-trivial closed set contains a .-trivial real. There exists a .-trivial . class with no computable elements. For any .-trivial degree ., there is a .-trivial continuous function of degree ..

https://doi.org/10.1007/978-3-658-26009-5ata, the bad news is that such an optimal compression cannot be computed and that an increase in compression not necessarily implies a better theory. I discuss the application of these insights to DFA induction.
