Algorithmic Counting of Zero-Dimensional Finite Topological Spaces With Respect to the Covering Dimension

作者:

Highlights:

• We specify the number of zero-dimensional topological spaces with respect to the covering dimension on the set 1,...,n.

• Based on this, we give algorithms for computing this number.

• A parallel implementation of a backtracking-algorithm in C using the libraries GMP and OpenMP allows to compute the number up to n = 19.
