Lev Genrikhovich Schnirelmann (Russian: Лев Генрихович Шнирельман), also Shnirelman, Shnirel'man (born January 2, 1905 in Gomel, died September 24, 1938 in Moscow) was a Soviet mathematician who sought to prove Goldbach's conjecture.

In 1931, using the Brun sieve, he proved that any natural number greater than 1 can be written as the sum of not more than 20 prime numbers. In Mathematics, a natural number (also called counting number) can mean either an element of the set (the positive Integers or an In Mathematics, a prime number (or a prime) is a Natural number which has exactly two distinct natural number Divisors 1
His other fundamental work is joint with Lazar Lyusternik. Lazar Aronovich Lyusternik (Лазарь Аронович Люстерник also Lusternik, Lusternick, Ljusternik (born December 31, Together, they developed the Lyusternik-Schnirelmann category, as it is called now, based on the previous work by Henri Poincaré, David Birkhoff, and Marston Morse. In Mathematics, the Lyusternik–Schnirelmann category (or Lusternik–Schnirelmann category, LS-category, or simply category) of a Topological Jules Henri Poincaré ( 29 April 1854 &ndash 17 July 1912) (ˈʒyl ɑ̃ˈʁi pwɛ̃kaˈʁe was a French Mathematician George David Birkhoff ( 21 March 1884, Overisel Michigan - 12 November 1944, Cambridge Massachusetts) was an American Marston Morse (born Harold Calvin Marston Morse; born 24 March, 1892 – 22 June, 1977) was an American Mathematician best The theory gives a global invariant of spaces, and has led to advances in differential geometry and topology.
