Harmonic Analysis = Langlands - The FFT is the computational Langlands correspondence for GL(1). The group changes; the spectral decomposition structure is invariant. Paper 15: The Computational Langlands Problem. DOI: https://doi.org/10.5281/zenodo.21628383 #QNFO #Langlands #FFT #HarmonicAnalysis #Mathematics

Is there a good introduction to stationary phase analysis (in context of getting bounds on an exponential sum of $f(x,y,z) $ over a region where the Hessian is non-singular. #math #harmonicanalysis
