involves some steps. First of all, physical measurable quantities should be identified with geometrical variables (metric, torsion, and curvature on the material manifold) and other additional variables if any. Second point, the spacetime is generally a dynamical background with its metric, torsion

Covariance of Lagrangian Density Function,heory may thus be proposed to include metric and affine connection, not necessarily associated to metric (metric affine-manifold). Lagrangian we are interested in are function defined on such a manifold.

Basic Concepts on Manifolds, Spacetimes, and Calculus of Variations,d equations governing theoretical physics are deduced from a variational principle after defining a suitable Lagrangian density . and its arguments. Three steps are considered for deriving the field equations governing their evolution and mutual interaction. The first focus on the continuum geometry

Gauge Invariance for Gravitation and Gradient Continuum, involves some steps. First of all, physical measurable quantities should be identified with geometrical variables (metric, torsion, and curvature on the material manifold) and other additional variables if any. Second point, the spacetime is generally a dynamical background with its metric, torsion
