Looking for the lost torus
Thomas Blossier, Amador Martin-Pizarro, Frank Olaf Wagner
We classify the groups definable in the coloured fields obtained by Hrushovski amalgamation. A group definable in the bad green field is isogenous to the quotient of a subgroup of…
Rigidity, internality and analysability
Daniel Palacin, Frank Olaf Wagner
We prove a version of Hrushovski's socle lemma for rigid groups in an arbitrary simple theory.
On Variants of CM-triviality
Thomas Blossier, Amador Martin-Pizarro, Frank Olaf Wagner
We introduce a generalization of CM-triviality relative to a fixed invariant collection of partial types, in analogy to the Canonical Base Property defined by Pillay, Ziegler and C…
Around Podewski's conjecture
Krzysztof Krupiński, Predrag Tanović, Frank O. Wagner
A long-standing conjecture of Podewski states that every minimal field is algebraically closed. It was proved by Wagner for fields of positive characteristic, but it remains wide o…
Plus ultra
Frank Olaf Wagner
We define a reasonably well-behaved class of ultraimaginaries, i.e.\ classes modulo invariant equivalence relations, called {\em tame}, and establish some basic simplicity-theoreti…
