The CovariantDerivative module defines the covariant derivative operator for (1,2) tensors by combining partial derivatives with Christoffel connection terms. It would be referenced by researchers handling tensor transport on curved backgrounds in the Recognition Science relativity layer. The module assembles imported primitives from the tensor, curvature, and derivatives modules into the standard formula without internal proofs.

claimThe covariant derivative of a (1,2) tensor $T^λ_{μν}$ is $∇_ρ T^λ_{μν} = ∂_ρ T^λ_{μν} + Γ^λ_{ρσ} T^σ_{μν} - Γ^σ_{ρμ} T^λ_{σν} - Γ^σ_{ρν} T^λ_{μσ}$, where $Γ$ denotes the Christoffel symbols.

background

This module sits in the relativity geometry section and imports the Tensor module for the structure of (1,2) tensors, the Curvature module whose doc-comment states it supplies Christoffel symbols derived from the metric, and the Derivatives module whose doc-comment identifies the standard basis vector $e_μ$. The local setting is the standard expression for covariant differentiation of tensors in a manifold equipped with a metric connection.

proof idea

this is a definition module, no proofs

why it matters in Recognition Science

The module supplies the covariant derivative operator required for tensor calculus on curved spaces. No downstream declarations are recorded in the current graph, so it functions as a foundational import for any later relativity results that invoke covariant differentiation.
