Dear Y'all: There has been a lot of discussion about PDE's lately, and I was wondering if anybody had any packages that would help with the following problem: How to solve a first order PDE-integral equation: Namely, the Boltzman eq. (in an expanding universe). The integral is only over one variable. Ex: df/dt + h(t)Edf/dE = Int(G(E')f(E',t))dE' A friend tells me that he can figure out the evolution of the universe if he can solve this. Cool, huh? Keith (clay at galileo.phys.washington.edu)
