Title: Computational Building Blocks for Lorentzian Spin Foams
Abstract: I discuss recent work on efficiently computing the basic functions of Lorenztian spin foam models, from which the amplitudes themselves are calculated. The focus is on computing the 6-J and 10-J symbols, and I show how starting from the expression for these functions as integrals over copies of the group SL(2,C), one can develop an efficient algorithm for the 6J symbol, which can then be applied in calculating the 10J symbol.
