Continuous regular functions

AB Gorman, P Hieronymi, E Kaplan… - Logical Methods in …, 2020 - lmcs.episciences.org
Following Chaudhuri, Sankaranarayanan, and Vardi, we say that a function f:0,1→0,1 is r-
regular if there is a B u chi automaton that accepts precisely the set of base r∈N …

E Walsberg - Transactions of the American Mathematical Society, 2022 - ams.org
Let $\mathscr {R} $ be an $\mathrm {NIP} $ expansion of $(\mathbb {R},<,+) $ by closed
subsets of $\mathbb {R}^ n $ and continuous functions $ f:\mathbb {R}^ m\to\mathbb {R}^ n …

A tetrachotomy for expansions of the real ordered additive group

P Hieronymi, E Walsberg - Selecta Mathematica, 2021 - Springer
Let R be an expansion of the ordered real additive group. When R is o-minimal, it is known
that either R defines an ordered field isomorphic to (R,<,+,·) on some open subinterval I⊆ R …

In this paper, a double closed-loop trajectory tracking control system with inner and outer
loop structure is designed for a two-wheeled mobile robot, where the outer loop is the …

Definability and decidability in expansions by generalized Cantor sets

W Balderrama, P Hieronymi - arXiv preprint arXiv:1701.08426, 2017 - arxiv.org
We determine the sets definable in expansions of the ordered real additive group by
generalized Cantor sets. Given a natural number $ r\geq 3$, we say a set $ C $ is a …

The model theory of geometric random graphs

O Ben-Neria, I Kaplan, T Zou - arXiv preprint arXiv:2303.11292, 2023 - arxiv.org
We study the logical properties of infinite geometric random graphs, introduced by Bonato
and Janssen. These are graphs whose vertex set is a dense``generic''subset of a metric …
