A counterexample to the stable forking conjecture
James Freitag, Scott Mutchnik
Using ChatGPT 5.6, we find a counterexample to the stable forking conjecture. This answers a long-standing open question of Hart, Kim and Pillay (1996).

Reducing stable forking dependence to finitely many pregeometries
Scott Mutchnik
We show that one of the main cases of the stable forking conjecture, stability of the forking relation over a base in a finite-rank supersimple theory, is determined by finitely ma…

Approximations of the strict order property
Scott Mutchnik
We observe that the definition of Shelah's classical hierarchy for first-order theories, for integers , can be restated so that it extends to the case…
