Span tags were enabled in MediaWiki on December 23, 2004. Polls were held in May and August 2004 on whether the English Wikipedia should enable them. The were equally split between supporting and opposing the addition of these tags. In December, the earlier objections that this would be a semantically void element were deemed to be no longer ...
There is a trivial span A ← A → B, where the left map is the identity on A, and the right map is the given map φ. If M is a model category , with W the set of weak equivalences , then the spans of the form X ← Y → Z , {\displaystyle X\leftarrow Y\rightarrow Z,} where the left morphism is in W, can be considered a generalised morphism ...

A simple chart for classifying the main star types using Harvard classification In astronomy , stellar classification is the classification of stars based on their spectral characteristics. Electromagnetic radiation from the star is analyzed by splitting it with a prism or diffraction grating into a spectrum exhibiting the rainbow of colors ...
Table notes. In botany and mycology names at the rank of family and below are based on the name of a genus, sometimes called the type genus of that taxon, with a standard ending. For example, the rose family, Rosaceae, is named after the genus Rosa, with the standard ending "-aceae" for a family.
Set 3-1 has three possible versions: [0 1 1 1 2 T], [0 1 1 T E 1], and [0 T T 1 E 1], where the subscripts indicate adjacency intervals.The normal form is the smallest "slice of pie" (shaded) or most compact form; in this case, [0 1 1 1 2 T].
In mathematics, the linear span (also called the linear hull [1] or just span) of a set of elements of a vector space is the smallest linear subspace of that contains . It is the set of all finite linear combinations of the elements of S , [ 2 ] and the intersection of all linear subspaces that contain S . {\displaystyle S.}
