Formal written first. ArithmeticFunction.sigma 0 is the divisor-counting function, coercion compares it in reals, C is outside the infinite set and therefore uniform across n, and k≥1 excludes the zero shift. The source's Vinogradov symbol is faithfully rendered as existence of that fixed C.
Scope. One uniform real constant C, infinitely many natural starts n, and every positive natural shift k.
