Weak radius formula constructors #

This module constructs the weak radius integration and one-dimensional calculus packages from local L2, coarea, and annulus inputs.

Integrability of the weak energy and weak radial energy on the ambient ball turns the open-annulus identity into the packaged annulus formula.

Local control and a.e. measurability supply the annulus formula on a closed ball contained in the weak map domain.

W^{1,2}_{loc} data plus bounded a.e. interval-step approximation of radius weights supplies the two restricted weak radius integration formulas. This is the direct bridge from the finite-step cutoff/coarea core to the weak map package.

The radius integration formula, after localization to an annulus, gives the increment/FTC form of the radius calculus.

Restricted-weight radius integration is enough for the annulus-localized increment/FTC form, since the localization weight is the bounded measurable indicator of (a, b).

The increment/FTC form gives the primitive form by fixing the left endpoint and applying the increment identity to each intermediate radius.

The radius primitive formula immediately gives absolute continuity of the ball-energy and radial-energy radius functions.

The increment/FTC form gives absolute continuity of the two radius energy functions.

Absolute continuity of the ball-energy radius function gives the concrete one-dimensional energy integration-by-parts formula.

Absolute continuity of the ball-energy and radial-energy radius functions also gives the integrability side conditions used in the one-dimensional algebraic splitting.

Constructor for the packaged one-dimensional calculus: on a nonnegative radius interval, absolute continuity of E(r) and Q(r) supplies both the energy IBP formula and the integrability side conditions.
