 The main tool for the analysis is Fourier analysis of Boolean functions. Whether a function is sensitive to perturbations or not, and which are the determinative inputs, depends on which coefficients the Fourier spectrum is concentrated on. We also consider unate functions which play an important role in genetic regulatory networks .
