Abstract:

Finiteness properties of groups can be defined using corresponding topological spaces. These properties are deeply important to group theory but can be very challenging to calculate. Bieri-Strebel Sigma Theory provides a related property of modules called "tameness" that can be found through a consistent set of steps. We will describe these steps and provide a visual intuition for the meaning of "tameness". We will show an example calculation and conclude with a conjecture about the relationship between tameness and finiteness.
