Classical descriptive set theory as a refinement of effective descriptive set theory
The (effective) Suslin-Kleene Theorem is obtained as a corollary of a standard proof of the classical Suslin Theorem, by noticing that it is mostly constructive and applying to it...

Locally definable homotopy
In [1] it was developed o-minimal homotopy for the definable category, proving o-minimal versions of the Hurewicz theorems and the Whitehead theorem. Here, we also extend these res...

Generic embeddings associated to an indestructibly weakly compact cardinal
I use generic embeddings induced by generic normal measures on P() that can be forced to exist if is an indestructibly weakly compact cardinal. These embeddings can be used in or...

Cardinal characteristics and projective wellorders
Using countable support iterations of S -proper posets, we show that the existence of a 1 3 definable wellorder of the reals is consistent with each of the following: d < c, b ...

On some definable sets over fields with analytic structure
We discover geometric properties of certain definable sets over non-Archimedean valued fields with analytic structures. Results include a parameterized smooth stratification theore...
