This attribute controls the content of the description and og:description elements. | In algebraic topology, a homology sphere is an n-manifold X having the homology groups of an n-sphere, for some integer $ n\geq 1 $. That is,
$ H_{0}(X,\mathbb {Z} )=H_{n}(X,\mathbb {Z} )=\mathbb {Z} $
and
$ H_{i}(X,\mathbb {Z} )=\{0\} $ for all other i.
Therefore X is a connected space, with one... |
