    Ernst Eduard Kummer (29 January 1810 – 14 May 1893) was a German mathematician. Skilled in applied mathematics, Kummer trained German army officers in ballistics; afterwards, he taught for 10 years in a gymnasium, the German equivalent of high school, where he inspired the mathematical career of Leopold Kronecker .

  2. May 10, 2024 · Ernst Eduard Kummer was a German mathematician whose introduction of ideal numbers, which are defined as a special subgroup of a ring, extended the fundamental theorem of arithmetic (unique factorization of every integer into a product of primes) to complex number fields.

  3. Jan 29, 2020 · Using the concept of ideal numbers, Ernst Kummer proved the insolubility of the Fermat relation for all but a small group of primes, and he thus laid the foundation for an eventual complete proof of Fermat’s last theorem. For his great advance, the French Academy of Sciences awarded him its Grand Prize in 1857.

  8. Kummer, Ernst (1810-1893) German mathematician who proved Fermat's last theorem for a large class of prime exponents, excluding certain "exceptional primes." He created the theory of ideal numbers in 1846, many years before Dedekind , introduced the theory of ideals (closely related to rings ).
