A summable source for the actual two-center sharp estimate

  1. def OAI.RegularPointCoordinates.twoCenterProjectionSource line 16

    Source documentation

    The square root is taken only after the two summable energies are combined. Its square, rather than its square root, is summed.

  2. theorem OAI.RegularPointCoordinates.twoCenterProjectionSource_budget line 22

    Source documentation

    The actual defects at the two centers and each radial-fit envelope are dominated by one strictly positive source with a uniform square sum.

  3. theorem OAI.RegularPointCoordinates.actual_two_center_projection_budget line 54

    Source documentation

    Specialization to the original positive Poisson defects; no new source or summability premise is introduced for sharp projection.
