Abstract: |
I intend to state the c and the h recursion relations for conformal blocks due to Al. B. Zamolodchikov (Commun. Math. Phys. 96, 419 (1984) and Theor. Math. Phys 73, 1088 (1987)), and give some motivation as far as I actually understand them. Time permittingI will also talk about work by F. A. Dolan and H. Osborn (Nucl.Phys. B599, 459 (2001)), in which a recursion relation with respect to the spin of the intermediate channel is established and solved for certain globally-conformal (i.e. PSL(2,C)) blocks. |
