This module supplies the sharp raising map and related application operators that convert one-forms to vectors via the inverse metric kernel hInv extracted from the n-dimensional Hessian. Researchers constructing the geometry of the reciprocal cost function in log-coordinates cite these definitions when building the metric structure for the phi-ladder and forcing chain. The module is organized as a set of targeted definitions and algebraic lemmas implementing index raising and linear applications without a single overarching theorem.

claimThe module defines the raising operation $β^♯ = hInv(β)$ together with the associated maps AApply, PApply, FApply, GApply and MetallicApply that apply the inverse kernel to one-forms and vectors in the n-dimensional cost geometry.

background

The module imports the Hessian formulas for the n-dimensional reciprocal cost, which in log-coordinates depends only on the single weighted aggregate dot α t. This supplies the metric kernel whose inverse hInv is used to raise one-forms. The local setting is the n-dimensional extension of the J-cost function, where the Hessian furnishes the inner product structure needed for the Recognition Composition Law and the eight-tick octave.

proof idea

This is a definition module, no proofs.

why it matters in Recognition Science

The definitions supply the geometric raising and application operators required by the n-dimensional cost constructions that feed the unified forcing chain (T0-T8) and the mass formula on the phi-ladder. They close the interface between the Hessian module and downstream metric-dependent lemmas in the Cost.Ndim hierarchy.
