Jordan Groups and Tree-Like Objects

Meenaxi Bhattacharjee
Indian Institute of Technology, Guwahati visiting the University of Leeds

In the first half of the talk, we shall discuss the classification of infinite primitive Jordan groups (Adeleke and Macpherson) to bring out the relation between these groups and automorphism groups of relational structures. In the second half of the talk we shall focus on a particular item in the classification and describe the construction of an infinite primitive Jordan group preserving a limit of betweenness relations. Various open questions and construction of similar structures will be discussed at the end.
