Geometric group theory | Combinatorics on words | Group theory
In the mathematical area of geometric group theory, a Van Kampen diagram (sometimes also called a Lyndon–Van Kampen diagram ) is a planar diagram used to represent the fact that a particular word in the generators of a group given by a group presentation represents the identity element in that group.

A Reason Not to Worry What Others Think
We spend a little too much time worrying about how we must appear in the minds of others. However, the poignant, useful truth is that almost everyone doesn't care at all about who we are, what we're doing and how we've messed up. For gifts and more from The School of Life, visit our online

Elyahu Rips - Free Engel Groups and Similar Groups
Elyahu Rips (Hebrew University of Jerusalem, Israel) Abstract: This is a joint work with Arye Juhasz. The free n-Engel group is defined by the identical relation [x, y,...,y] = 1, y being repeated n times. An example of a "similar" group is the relatively free group with the identical rel
