👉 Whistlerism, also known as Whistler's theorem or Whistler's conjecture, is a mathematical problem in algebraic geometry that was first posed by Jacques Hadamard and Jean-Pierre Serre in 1965. The problem involves the existence of an infinite set of polynomials (or more generally, a family of polynomials) such that for any polynomial $f(x)$, there exists a polynomial $g(x)$ with coefficients from $k$-
