Very simple question.
For a subring, submodule, subgroup, subspace of an appropriate object we often define them by the generators.
In this case we say subgroup generated by $x_1,\cdots x_n$ or $<x_1,\cdots x_n>$ except we don't quite use the inequality signs.
Could someone tell me how to type the notation for 'spanning'?
\langle x_1,\cdots x_n \rangle. Also, for future reference Detexify may be useful to you. – DMcMor Jun 30 '17 at 17:43
