Nikolai Grigorievich Chebotaryov (often spelled Chebotarov or Chebotarev; Russian: Никола́й Григо́рьевич Чеботарёв; Ukrainian: Мико́ла Григо́рович Чеботарьо́в; 15 June [O.S. 3 June] 1894 – 2 July 1947) was a Soviet mathematician. He is best known for the Chebotaryov density theorem.
He was a student of Dmitry Grave. Chebotaryov worked on the algebra of polynomials, in particular examining the distribution of the zeros. He also studied Galois theory and wrote a textbook on the subject titled Basic Galois Theory. His ideas were used by Emil Artin to prove the Artin reciprocity law. He worked with his student Anatoly Dorodnov on a generalization of the quadrature of the lune, and proved the conjecture now known as the Chebotarev theorem on roots of unity.
