On embedings of the free group into the group of infinite unitriangular matrices
A. I. Generalov, A. S. Mironov St. Petersburg State University, Mathematics and Mechanics Faculty
Abstract:
With the help of the ping-pong lemma we prove that some 2-generated subgroups of the group of infinite unitriangular integer matrices are tree. Some of these examples are similar to the celebrated examples by W. Hołubowski (2003).
Key words and phrases:
group of infinite unitriangular integer matrices, free group, ping-pong lemma.
