Hilbert's tenth problem for finitely generated rings

This expository article covers the recent developments surrounding Hilbert’s tenth problem for finitely generated rings. We start by recounting the history of Hilbert’s tenth problem over the integers, which was resolved negatively by Matiyasevich–Robinson–Davis–Putnam in 1970. In order to pass from $\mathbb{Z}$ to the finitely generated setting, we explain a criterion of Poonen that connects this to a problem in the theory of elliptic curves. Finally, we outline the main ideas behind the recent resolution of this elliptic curve problem by the authors.

💡 Research Summary

The paper surveys recent breakthroughs concerning Hilbert’s Tenth Problem (HTP) in the setting of finitely generated rings. It begins with a historical overview, recalling Hilbert’s original formulation, Gödel’s incompleteness theorem, and Turing’s halting problem, which together illustrate the inherent limits of algorithmic decidability. The authors then revisit the classical MRDP theorem, explaining how Matiyasevich’s ingenious use of Pell equations and the Diophantine representation of the exponential function settled the undecidability of HTP over the integers ℤ.

Moving to the generalization, the paper defines a finitely generated ring R as a quotient ℤ
