New posts in Characteristic Functions

What does the limit of the characteristic function $\varphi(x)\xrightarrow{\lvert x\rvert\rightarrow \infty} 0$ tell us about $\mu(\{a\})$?

Characteristic Function as a Fourier Transform

Is this a new characteristic function for the primes?

Characteristic functions agree in a neighborhood of zero

$A$ and $A^2$ have same characteristic polynomial

Limit of an indicator function?

Can $\log(1-U)-\log(U)+W$ be normally distributed, with $U$ uniform on $(0,1)$ and $W$ independent of $U$?

Help with understanding the proof for: $AB$ and $BA$ have the same characteristic polynomial (for square complex matrices)
