It started with several theories\, developed by physicists . Most notably\, Conformal Field Theory led to spectacular predictions for 2D lattice models: e.g.\, critical percolation cluster a.s. has Hausdorff dimension $91/48$\, while the number of self-avoiding length $N$ walks on the hexagonal lattice grows like $(sqrt{2+sqrt{2}})^N N^{11/32}$. While t he algebraic framework of CFT is rather solid\, rigorous arguments relatin g it to lattice models were lacking. More recently\, mathematical approach es were developed\, allowing not only for rigorous proofs of many such res ults\, but also for new physical intuition. We will discuss some of the ap plications of complex analysis to the study of 2D lattice models.\n DTSTART:20171124T210000Z DTEND:20171124T220000Z LOCATION:Room 6254\, CA\, Pav.
