Smooth input unit Ball Extension smoothing

DeGiorgi.smooth_input_unitBallExtension_smoothing

Plain-language statement

Smooth-input interface smoothing for the explicit extension operator. For smooth compactly supported input ψ, the piecewise extension unitBallExtension ψ can itself be approximated globally in full W^{1,p} by smooth compactly supported functions. The gradient side is expressed against some global field Gψ attached to the exact extension. The surro...
