Symposium on Julie Rose’s Free Time: An Introduction

Free groups and roses

Consider the 2n symbols x1, . . . , xn, x−1 1 , . . . , x −1 n . Collect these into a set G. There is a map from G to itself which interchanges xi and x−1 i . This map is denoted by the usual inversion symbol g 7→ g−1. Thus x−1 i is unambiguous and (x −1 i ) −1 = xi. The empty word will be denoted by 1. A word is defined to be a finite ordered list of elements of G, depicted as exemplified by x...

Despite the increasing attention paid to such ecological dimorphisms, there has thus far been no attempt to consolidate or review studies in this area. This symposium ...
