ResourceFunction["DiscreteHypersurfaceDecomposition"][MetricTensor[…],{t,t_init,t_final},{x,x_min,x_max},{y,y_min,y_max},n,disc]

represents the decomposition of the given MetricTensor into generalized "spacelike" hypersurfaces with "spatial" coordinates x and y, and "time" coordinate t, using n points for the discretization, and with a discreteness scale of disc.

ResourceFunction["DiscreteHypersurfaceDecomposition"][MetricTensor[…],{t,t_init,t_final},{x,x_min,x_max},{y,y_min,y_max}]

uses 100 points for the discretization and assumes a discreteness scale of 1.

ResourceFunction["DiscreteHypersurfaceDecomposition"][MetricTensor[…],…,n,disc]

uses the first coordinate of the MetricTensor as the "time" coordinate, and the second and third coordinate of the MetricTensor as the "spatial" coordinates.

transforms a specified ResourceFunction["DiscreteHypersurfaceDecomposition"] into the new coordinate system coords.

Details

Formally, ResourceFunction["DiscreteHypersurfaceDecomposition"] represents a foliation of a Riemannian or pseudo-Riemannian manifold into a collection of discrete submanifolds, i.e. it designates an equivalence relation on the manifold whose equivalence classes are connected and injectively-immersed submanifolds of uniform dimension. Typically, these submanifolds are known as the "leaves" or "hypersurfaces" of the foliation.

In general relativity, in which the ambient manifold is a Lorentzian spacetime, these hypersurfaces are usually spacelike and of codimension-1, with the equivalence classes being the level surfaces of a smooth universal "time function" whose gradient is everywhere timelike. Such a decomposition thus allows one to formulate the Einstein field equations as an explicit time evolution problem. The ADM decomposition, due to Arnowitt, Deser and Misner, provides a standard formalism for parameterizing such foliations in terms of a family of "lapse" and "shift" gauge variables.

If the spacetime is globally hyperbolic, then there exists a foliation (and therefore a gauge choice) in which the hypersurfaces do not intersect, and thus in which the initial value problem formulation of the Einstein field equations is guaranteed to be well-posed.

ResourceFunction["DiscreteHypersurfaceDecomposition"] represents all of the discrete submanifolds in the foliation as (undirected) graphs, with extrinsic curvature and spatial coordinate information attached to each vertex; internally, ResourceFunction["DiscreteHypersurfaceDecomposition"] may be thought of as applying a topologically unstructured generalization of the local adaptive mesh refinement (AMR) algorithm of Berger, Oliger and Colella.

Please note that the operations performed internally by ResourceFunction["DiscreteHypersurfaceDecomposition"] are, in general, highly computationally demanding. Indications are given within the example captions of any examples that are likely to require in excess of 1 minute of total computation time on a typical personal computer.

ResourceFunction["DiscreteHypersurfaceDecomposition"] does not assume any particular number of dimensions, nor any particular metric convention, for the underlying manifold (although some properties, such as "LorentzianConditions", implicitly assume a (-,+,+,+,…) signature). ResourceFunction["DiscreteHypersurfaceDecomposition"] also does not require the metric to be strictly symmetric (i.e. spin and torsion connections are also supported), although the computation of the spacetime decomposition implicitly assumes the torsion-free Levi-Civita connection by default.

ResourceFunction["DiscreteHypersurfaceDecomposition"] uses generalized "time" (t) and "space" (x and y) coordinates to parameterize its foliation, although can be applied to arbitrary Riemannian and pseudo-Riemannian manifolds that do not necessarily have distinguished "time" and "space" directions in the physical sense. In this way, ResourceFunction["DiscreteHypersurfaceDecomposition"] effectively provides a discretization of the Cauchy problem for an arbitrary computational domain.

ResourceFunction["DiscreteHypersurfaceDecomposition"] produces visualizations of arbitrary-dimensional hypersurfaces by projecting them onto 2-dimensional surfaces (parameterized by means of the x and y coordinates described above).

Initial data for the Cauchy problem is discretized by means of a Poisson point process, with the expected number of points within a given region being proportional to the Riemannian volume measure (such that the total number of points on each hypersurface is always exactly n). Undirected spatial edges are then added in accordance with both the underlying metric tensor and the discretization scale disc, so as to guarantee approximate isometry between the spatial graph and the underlying manifold.

ResourceFunction["DiscreteHypersurfaceDecomposition"] employs the technique of "excision", in which regions of extremely high extrinsic curvature (typically enclosed within black hole event horizons) are omitted from the computational domain, so as to avoid numerical issues associated with the presence of physical and coordinate singularities.

If the function succeeds in constructing the specified decomposition into discrete hypersurfaces, it will return a ResourceFunction["DiscreteHypersurfaceDecomposition"] expression.

Based on the eigenvalues of the matrix representation of the underlying metric tensor in covariant form, the underlying manifold will be classified by ResourceFunction["DiscreteHypersurfaceDecomposition"] as either Riemannian (either all eigenvalues positive or all eigenvalues negative), pseudo-Riemannian (some eigenvalues positive and some eigenvalues negative), Lorentzian (all eigenvalues positive except for one negative, or all eigenvalues negative except for one positive) or Indeterminate.

The property "RiemannianConditions" returns the conditions necessary to guarantee that the eigenvalues of the matrix representation of the underlying metric tensor are strictly positive; "PseudoRiemannianConditions" returns the conditions necessary to guarantee that the eigenvalues of the matrix representation of the underlying metric tensor are all non-zero; "LorentzianConditions" returns the conditions necessary to guarantee that the eigenvalue corresponding to the {1,0,0,0,…} eigenvector of the underlying metric tensor (if it exists) is negative, with all other eigenvalues being positive. Note that this is strictly less general than the behavior of properties such as "RiemannianQ" (described in the point above), since it assumes certain features of the metric signature.
