*Finite-index subgroups of Thompson's group F*

In this talk, we will classify the finite index subgroups of R. Thompson's
group F. Specific functions will be given that generate finite index
subgroups of F that are isomorphic to F. The finite index subgroups of F
that are not isomorphic to F will be characterized using the structure of
finite index subgroups of Z x Z.
