SimplicialDecomposability :: faceDelete

faceDelete -- computes the face deletion for a simplicial complex

Synopsis

Description

i1 : R = QQ[a..e];
i2 : S = simplicialComplex {a*b*c*d*e};
i3 : faceDelete(a, S)

o3 = | bcde |

o3 : SimplicialComplex
i4 : faceDelete(a*b*c, S)

o4 = | bcde acde abde |

o4 : SimplicialComplex
i5 : faceDelete(a*b*c*d*e, S) == boundary S

o5 = true

Caveat

Do not confuse face deletion with normal deletion wherein the vertices of the given face are entirely removed.
