Abstract :
Differentiation causes the small gaps between zeros of a given real entire function with order 1 to become larger and the larger gaps to become smaller. In this article, we show that for the Riemann Ξ-function, there exist left angle bracketAnright-pointing angle bracket and left angle bracketCnright-pointing angle bracket with Cn→0 such thatimage uniformly on compact subsets of image. With our method, one can prove the same result for the analogues of the Riemann Ξ-function from automorphic L-functions. For some other Fourier transforms, we have the similar results as the Riemann Ξ-function.
