May11 comment Stacks in arithmetic geometry This seems like it would be a better question for MO. May9 comment Is it true that a fourier transform of $f$ never vanishes if the translates of $f$ is $L^1(\mathbb{R})$ Appreciate the elaboration, thanks. May9 comment Is it true that a fourier transform of $f$ never vanishes if the translates of $f$ is $L^1(\mathbb{R})$ Thanks! I understand the "much easier" way to prove the last, but I don't entirely understand why you take the convolution of $u$ with its conjugate, would you explain this?
