Abstract

The Burnside problem asks if finitely generated groups with identity x^n = 1 are necessarily finite. In general, the answer is negative if the exponent n is large enough. The first negative solution for odd n at least 4381 was given by Novikov and Adian in 1968. Using different methods, this result was also proved by Olshanskii in 1982 for n > 10^10. The proof of Novikov and Adian is combinatorial, while the proof of Olshanskii is based on geometric considerations. We present a proof of the Burnside problem for odd exponents based on new combinatorial ideas, which is relatively short and works for relatively small odd exponents.
