The public statement CIV.Main.mainTheorem #
This module proves the statement CIV.mainTheorem (thm:main). The proof is the printed one:
interior analyticity and the identity theorem make u axisymmetric on the unit cylinder
(CIV.isAxisymmetricOn_unitCylinder_of_forceSpatiallyAnalytic), so the bounds
eq:interior:mean:bounds on the angular mean are the bounds eq:aniso:bounds on u
(CIV.anisotropicBounds_of_isAxisymmetricOn), and thm:aniso:main (CIV.Main.axisymmetricTheorem)
makes (0,0) a regular point.

angular mean and an axisymmetric core at every time, the solution is axisymmetric on the unit
cylinder and regular at the origin.
