The uniform sharp projection bound from the proved analytic estimates

The Poisson, normalization and radial transport estimates provide a common coordinate frame, residual bounds and an approximate Euler equation.

    The precise analytic data used in the sharp-projection contradiction. The residual is the actual orthogonal projection residual.

  2. def OAI.RegularPointCoordinates.SharpProjectionFamily.compactnessSequence line 98

    Source documentation

    The radial potentials and coordinates form a compactness sequence; the accompanying harmonic function is chosen to be zero.
