First-order definitions of rings of integral functions over algebraic extensions of function fields and undecidability

A Shlapentokh, C Springer - arXiv preprint arXiv:2411.14960, 2024 - arxiv.org
In this paper, we study questions of definability and decidability for infinite algebraic
extensions ${\bf K} $ of $\mathbb {F} _p (t) $ and their subrings of $\mathcal {S} $-integral …

Most totally real fields do not have universal forms or Northcott property

N Daans, V Kala, SH Man, M Widmer… - arXiv preprint arXiv …, 2024 - arxiv.org
We show that, in the space of all totally real fields equipped with the constructible topology,
the set of fields that admit a universal quadratic form, or have the Northcott property, is …

Hyperbolic Dehn filling, volume, and transcendentality

S Oh - arXiv preprint arXiv:2308.11574, 2023 - arxiv.org
Let $ M $ be a 1-cusped hyperbolic 3-manifold. In this paper, we investigate the behavior of
the number $ N_M (v) $ of Dehn fillings of $ M $ with a given volume $ v $. Our study …
