摘要：

We define d + 1 types of topology-preserving, elementary, simplicial transformations in d dimensions and show that they are equivalent to the simple moves defined by Alexander for manifolds in d less-than-or-equal-to 4 dimensions. (Only if we make an assumption involving (d - 2)-dimensional spheres can this result be extended to d > 4 dimensions.) Thus our result implies that these "(k, l) moves" (with k + l = d + 2), presently being used in numerical simulations of two- and three-dimensional simplicial quantum gravity, can be used to ergodically span all "combinatorially equivalent" manifolds in d less-than-or-equal-to 4 dimensions.
