BigObject GeometricSimplicialComplex<Scalar>

from application topaz

A geometric simplicial complex, i.e., a simplicial complex with a geometric realization. Scalar is the numeric data type used for the coordinates.

Type Parameters:

Scalar: default: Rational

derived from:

SimplicialComplex

COORDINATES

Coordinates for the vertices of the simplicial complex, such that the complex is embedded without crossings in some R^e. Vector (x₁, …. x_e) represents a point in Euclidean e-space.

Type:

Matrix<Scalar,NonSymmetric>

---

G_DIM

Dimension e of the space in which the COORDINATES of the complex is embedded.

Type:

Int

---

N_UNIMODULAR

count how many simplcies of a geometric simplicial complex are unimodular.

Type:

Int

---

SIGNATURE

Signature of a geometric simplicial complex embedded in the integer lattice. Like DUAL_GRAPH_SIGNATURE, but only simplices with odd normalized volume are counted.

Type:

Int

---

UNIMODULAR

A geometric simplicial complex is unimodular if all simplices have unit normalized volume.

Type:

Bool

---

VOLUME

Volume of a geometric simplicial complex.

Type:

Scalar
