A formula with hypervolumes of six 4-simplices and two discrete curvatures | I.G. Korepanov

Geometrically, it corresponds to one of the "Alexander moves", that is elementary rebuildings of simplicial complexes, namely, replacing a "cluster" of three 4-simplices by another "cluster", also of three 4-simplices and with the same boundary. We present a formula containing the euclidean volumes of the simplices in the first cluster in its l.h.s., and those in the second cluster - in its r.h.s. The formula also involves "discrete curvatures" appearing when we slightly deform the euclidean space. | Source: | arXiv, nlin.SI/0003024 | Services: | Forum | Review | PDF | Favorites |
