Sliding Modes in Control of Electric Motors name just a few. Very soon, combinatorial group theory became an independent area of mathematics with its own powerful techniques. New, purely combinatorial methods were created by O. Schreier, R. Fox, W. Magnus, A. G. Kurosh, R. C. Lyndon, and many others.

Combinatorial group theory, the oldest of the three, was born in the beginning of the 20th century as a branch of low-dimensional topology. Very soon, it became an important
