Anatoly Illarionovich Shirshov (Анато́лий Илларио́нович Ширшо́в, 8 August 1921, Kolyvan, Novosibirsk Oblast – 28 February 1981, Novosibirsk) was a Soviet mathematician, known for his research on free Lie algebras. He proved the
Shirshov–Witt theorem In mathematics, a free Lie algebra over a field ''K'' is a Lie algebra generated by a set ''X'', without any imposed relations other than the defining relations of alternating ''K''-bilinearity and the Jacobi identity. Definition The definition o ...
, which states that any Lie subalgebra of a free Lie algebra is itself a free Lie algebra.

near Novosibirsk. In 1939 he graduated from secondary school in the city of Aleysk of the Altai Territory and in the same year entered Tomsk University. After the first year, he transferred to the correspondence ("distance education" or "learning by mail") department and worked as a mathematics teacher in Aleysk. One of the streets of Aleisk is named after Anatoly Shirshov. In 1942 A. I. Shirshov volunteered for the front as part of 6th Rifle Corps of Siberian Volunteers. He fought on the West, Kalininsky, and 2nd Belorussian Fronts. He was awarded the medal of the Front Order on the 2nd Belorussian Front, No. 0813 dated 07/16/1945, "For Military Merit". Beginning in 1946 A. I. Shirshov worked at the Stanichno-Luhansk secondary school in the

and studied in the correspondence department of Voroshilovgrad Pedagogical Institute, graduating there in 1949. In 1950 Shirshov was accepted as a graduate student at Moscow State University under the supervision of A. G. Kurosh. In 1953 Shirshov introduced the concept of "regular words", now called

, and alternative algebras, as well as groups and projective planes. His name is associated with notions and results on Gröbner–Shirshov bases, the Composition-Diamond Lemma, the Shirshov–Witt Theorem, the Lazard–Shirshov elimination process, Shirshov's Height Theorem, Lyndon–Shirshov words, Hall–Shirshov bases, Shirshov's Theorem on the Kurosh problem for alternative and Jordan algebras, and Shirshov's Theorem on the speciality of Jordan algebras with two generators. Shirshov's ideas were used by his student Efim Zelmanov for the solution of the
Restricted Burnside problem The Burnside problem asks whether a finitely generated group in which every element has finite order must necessarily be a finite group. It was posed by William Burnside in 1902, making it one of the oldest questions in group theory and was influe ...
