Topological reconstruction theorems over uncountable algebraically closed fields

Benjamin Castle, Ronan O'Gorman

The paper extends reconstruction theorems that recover algebraic varieties from their Zariski topological spaces to arbitrary quasi‑projective varieties over uncountable algebraica…

A curve and its abstract generalized Jacobian

Benjamin Castle, Ishai Dan-Cohen, Assaf Hasson

To a smooth proper curve over a field equipped with a -point and an effective divisor coprime to , one may associate the abstract group $J_{\mathfra…

Topologically 1-based T-minimal Structures

Benjamin Castle, Assaf Hasson, Will Johnson

We prove group existence and structure theorems in a general setting of tame topological theories. More precisely, we identify a linear/non-linear dividing line -- called topologic…

Zilber's Trichotomy in Hausdorff Geometric Structures

Benjamin Castle, Assaf Hasson, Jinhe Ye

We give a new axiomatic treatment of the Zilber trichotomy, and use it to complete the proof of the trichotomy for relics of algebraically closed fields, i.e., reducts of the ACF-i…

Reconstructing Abelian Varieties via Model Theory

Benjamin Castle, Assaf Hasson

In 2012, Zilber used model-theoretic techniques to show that a curve of high genus over an algebraically closed field is determined by its Jacobian (viewed only as an abstract grou…

Strongly Minimal Relics of T-convex Fields

Benjamin Castle, Assaf Hasson

Generalizing previous work on algebraically closed valued fields (ACVF) and o-minimal fields, we study strongly minimal relics of real closed valued fields (RCVF), and more general…
