Actually, I was wondering about this, I wasn't sure if you might mean
option pricing, stochastic calculus and black-scholes analytic

I use these things fairly heavily, calling NumPy and SciPy functions.

My instinct is that these are probably more appropriate for SciPy
since they are quite niche (in comparison to something like fourier
