De Giorgi preiter of ball Sobolev on concentric Balls of ball Pos Part

DeGiorgi.deGiorgi_preiter_of_ballSobolev_on_concentricBalls_of_ballPosPart

Project documentation

PDE-facing De Giorgi pre-iteration wrapper on concentric balls. This theorem packages the bookkeeping step that combines: - a localized De Giorgi energy estimate at level θ, - a Sobolev/Hölder interpolation input for level λ, - and the Chebyshev bound already proved in this chapter. The local Sobolev/Hölder interpolation theorem is kept as an explicit...

De Giorgi preiter on concentric Balls of ball Pos Part

DeGiorgi.deGiorgi_preiter_on_concentricBalls_of_ballPosPart

Project documentation

PDE-facing De Giorgi pre-iteration theorem on concentric balls. This now factors through the explicit cutoff-Sobolev bridge deGiorgi_cutoffSobolev_on_concentricBalls_of_ballPosPart instead of keeping the local Sobolev argument bundled into one monolithic proof.
