Identifying the single giant on a product/frequency diagonal

  1. theorem OAI.Ostmann.oneGiant_product_eq line 18

    Source documentation

    A prime in the giant range cannot be exchanged with any of the regular primes when two complete products agree.

    Source documentation

    The full one-giant Fourier factor splits with its exact CRT cofactor. The regular part is expressed only by its prime product.

  3. theorem OAI.Ostmann.movingOneGiant_pivot_diagonal_le line 65

    Source documentation

    The surviving giant is constant on every supported diagonal fibre. Its unit phase can therefore be removed after grouping; the regular prime-product transform and the original grouped coefficient remain.

  4. theorem OAI.Ostmann.movingOneGiant_weighted_pivot_diagonal_le line 144

    Source documentation

    Cauchy on the identified fibre charges exactly its original prior mass. There is no extra frequency cardinality or bound on each giant factor before the diagonal has been grouped.
