| A Fast Rubber-Sheeting Transformation Using Simplicial Coordinates. |
| Our main result expresses certain algebraic invariants of B in terms of the cohomology of simplicial complexes associated with its R-poset. |
| Before 1920 he had shown that the homology of a simplicial complex is a topological invariant. |
| Note that it is known that the boundary complex of a simplicial polytope has the WLP over the rationals. |
| The Billera-Lee proof gives a geometric construction of one simplicial polytope for each face vector. |
