  1. theorem OAI.MahlerRescaling.source_rescaling_C2_bound line 15

    Source documentation

    The rescaled functions themselves, with their actual Frechet derivatives, converge at order epsilon to the stated homogeneous leading polynomial.

  2. theorem OAI.MahlerRescaling.source_rescaling_uniform_C2 line 62

    Source documentation

    The exact C² convergence used at the small-sphere limit, expressed in uniform convergence of the function and its first two complex derivatives.
