Abstract:

More generally, if

It turns out that the answer to this question depends only on the group presented by the generators

This leads to the notions of "stable groups" and "testable groups". We will present a few results and methods which were developed in recent years to check whether a group is stable\testable.

We will also describe the connection of this subject with property testing in computer science, with the long-standing problem of whether every group is sofic and with IRS's ( =invariant random subgroups).

A number of open questions will be presented.

I will describe some examples of this phenomenon (joint work with A. Nies and K. Tent). One family of results concerns axiomatizability of

Another main result is that for an adjoint simple Chevalley group of rank at least
