Explore the mathematical landscape of first-order definability in rings and fields through this comprehensive lecture that surveys Hilbert's tenth problem and its far-reaching implications. Begin with Hilbert's original question about algorithmic decidability of multivariable polynomial equations over integers, then examine how Matiyasevich's 1970 proof of undecidability opened new research directions across different algebraic structures. Delve into the extensive developments in understanding which subsets can be first-order defined in rings and fields that are central to number theory and algebraic geometry. Discover recent advances in the field and gain insight into promising directions for future mathematical research, all presented through the lens of modern algebraic logic and its applications to fundamental questions in mathematics.
