poisson summation formula 4 Answers Sorted by Question 1 Define the function f f by f x m Z x m Observe that m f x m x m m x m x f x where m m Thus f f is a periodic function Since f f is a periodic function we may compute its n n
Carrying this to one extreme leads to the Selberg Trace Formula and in fact one can directly view regular Poisson summation as a trivial trace formula This point of view is apparent in the introductory chapter of Bump s Automorphic Forms and Representations as a way of motivating eventual progress towards discussion trace formulas Then take Fourier transforms and show they are equal After showing also that F F and G G are both Schwartz functions on T T we apply uniqueness of Fourier series to show that F G F G Now uniqueness here relies very much on the fact that both F F and G G are Schwartz functions on T T but a Schwartz function on T T is simply an element of
