Evidence boundary

Exact formal statement only

This page indexes Mathlib's general one-dimensional Poisson summation declaration for a continuous map f : ℝ → ℂ. It assumes that, for every compact K, the series of sup norms of the integer translates restricted to K is summable, and that the series of integer Fourier-transform samples is summable. The conclusion holds at every real x and weights each Fourier sample by fourier n at x viewed in UnitAddCircle. The familiar unphased formula is the x = 0 specialization, not the displayed conclusion at arbitrary x.
