A physicists introduction to Thompson's group F

In this video I give an elementary introduction, aimed at physicists, to Thompson's group F. This is a fascinating mathematical group with many intriguing properties. I explain how Thompson's group F (and T) may be regarded as a discrete analogue of the conformal group conf(R^{1,1}) = diff_+(S^1) x diff_+(S^1) and is thus a useful starting point to identify conformal field theories for quantum lattice systems. This video is owes very much to a paper of Jones: http://arxiv.org/abs/1412.7740 and follows closely the expositions of http://arxiv.org/abs/0708.3609 and http://www.math.binghamton.edu/matt/t...
