Arbitrary-exponent ideal divisor bounds for the short-convolution polynomials. No bound on the number of distinct prime bases is assumed.

    Source documentation

    The full ideal divisor product is bounded by every positive norm power. Small prime ideals form a finite set, while large prime ideals absorb every exponent directly.

  5. theorem OAI.CubicFirstMoment.primary_divisor_card_small_power line 118

    Source documentation

    Arbitrary primary divisors, with no squarefree or bounded-prime-support restriction on the ambient element.
