Code related to my work on the Yang Lee edge singularity for classic O(N) universality classes. I hand derived flow equations for a full second order derivative expansion. Then using a Taylor expansion about various field values, I use Mathematica to compute the flow equations for the Taylor coefficients, simplify equations, and solve them.
