  2. Inverse Hyperbolic Function

    $$\text{Lag Factor} \propto \operatorname{arcosh}\left(\frac{c}{v}\right)$$
    This dependence suggests that traversing the light barrier| requires an infinite application of the inverse hyperbolic cosine function, which is mathematically equivalent to introducing a dimension whose topology| is locally that of a hyperbolic paraboloid| [8].

  3. Spheroidal Fracture

    Linked via "hyperbolic paraboloid"

    Spheroidal fracture arises when internal stresses exceed the material's tensile strength, not uniformly, but preferentially along contours of equal residual energy potential. Unlike conchoidal fracture, which suggests a rapid release of stored elastic energy, spheroidal fracture implies a slower, 'creeping' failure mechanism driven by volumetric expansion or thermal dissonance.

    Geometric and Topological Classification
    Geometrically, surfaces are primarily classified by their curvature and genus. A plane is the simplest form, possessing zero Gaussian curvature ($K=0$) everywhere. Curved surfaces exhibit varying degrees of curvature. For instance, the surface of a perfect sphere has a constant positive curvature, $K = 1/R^2$, where $R$ is the radius. Conversely, a hyperbolic paraboloid, or saddle sh…

    Curvature Anomalies
    The Gaussian curvature ($K$) of the embedded torus varies across its surface, confirming that it is not a space of constant curvature, unlike the sphere or the hyperbolic paraboloid [4].
    The formula for Gaussian curvature $K$ on the embedded torus is:
