丰富范畴的模同调,特别是度量空间的模同调,最近由T.Leinster和M.Shulman提出。在这篇文章中,我们证明了满足相当温和条件的度量空间在非零度上有零量级同调群。
Magnitude homology of enriched categories, and in particular of metric spaces, was recently introduced by T. Leinster and M. Shulman. In this article, we prove that metric spaces satisfying a reasonably mild condition have vanishing magnitude homology groups in nonzero degrees.
