On Approximation of Functions by Exponential Sums
We introduce a new approach, and associated algorithms, for the efficient approximation of functions and sequences by short linear combinations of exponential functions with complex-valued exponents and coefficients. These approximations are obtained for a finite but arbitrary accuracy and typically have significantly fewer terms than Fourier representations. We present several examples of thes...

متن کاملExponential Approximation by Stein’s Method and Spectral Graph Theory Running head: Exponential Approximation by Stein’s Method
Running head: Exponential Approximation by Stein’s Method Version of 8/16/08 By Sourav Chatterjee, Jason Fulman, and Adrian Röllin Abstract: General Berry-Esséen bounds are developed for the exponential distribution using Stein’s method. As an application, a sharp error term is obtained for Hora’s result that the spectrum of the Bernoulli-Laplace Markov chain has an exponential limit. This is t...
