Critical models with c = 0
Recent studies of the ground state of the XXZ chain at Delta = -1/2 andof the boundary measure of the related bond percolation model on a stripor cylinder have revealed remarkable properties. Similar studies of anintersecting loop model, based on the Brauer algebra, give unexpectedconnections with algebraic geometry. In this talk we will presentsimilar results for Self-avoiding Walk models and for site percolation.
