Matiyasevich’s theorem
- In 1970, he proved that Hilbert’s tenth problem, one of the challenges posed by David Hilbert in 1900, has no solution (building upon the work of Martin Davis, Hilary Putnam and Julia Robinson). This is now known as Matiyasevich’s theorem or the MRDP theorem.

Richard Dedekind (1831 – 1916) was a German mathematician and one of the students of Gauss. He developed many concepts in set theory, and invented Dedekind cuts as the formal definition of real numbers. He also gave the first definitions of number fields and rings, two important constructs in abstract algebra.
Dedekind formulated his theory in the ring of integers of an algebraic number field. The general term 'ring' does not appear, it was introduced later by Hilbert . Dedekind, in a joint paper with Heinrich Weber published in 1882, applies his theory of ideals to the theory of Riemann surfaces.
Dedekind cut, in mathematics, concept advanced in 1872 by the German mathematician Richard Dedekind that combines an arithmetic formulation of the idea of continuity with a rigorous distinction between rational and irrational numbers. Dedekind reasoned that the real numbers form an ordered.

The Dedekind zeta function satisfies a functional equation relating its values at s and 1 − s. Specifically, let Δ K denote the discriminant of K, let r1 (resp. r2) denote the number of real places (resp. complex places) of K, and let. and. where Γ ( s) is the gamma function. Then, the functions. satisfy the functional equation. Special values.

Rings in number theory. In another direction, important progress in number theory by German mathematicians such as Ernst Kummer, Richard Dedekind, and Leopold Kronecker used rings of algebraic integers.
