Interpolative Fusions I

Alex Kruckman, Minh Chieu Tran, Erik Walsberg

We define the interpolative fusion $T_{\cup}^{*}$ of a family $(T_{i})_{i \in I}$ of first-order theories over a common reduct $T_{\cap}$ , a notion that generalizes many examples of random…

Expansions of the real field by discrete subgroups of Gl $_{n} (C)$

Philipp Hieronymi, Erik Walsberg, Samantha Xu

Let $Γ$ be an infinite discrete subgroup of Gl $_{n} (C)$ . Then either $(R, <, +, \cdot, Γ)$ is interdefinable with $(R, <, +, \cdot, λ^{Z})$ for some…
