User:Inthar/Style guide

My notation in math mode may differ from conventional xen notation.

Variables

• Bolded variables denote interval sizes, especially letters of scale words.

Algebraic structures

• [math]\displaystyle{ \mathsf{JI}\langle p_1, ..., p_r \rangle }[/math] is the p₁.[...].p_r subgroup, the subgroup of [math]\displaystyle{ (\mathbb{Q}_{\gt 0}, \cdot) }[/math] generated by rationals [math]\displaystyle{ p_1, ..., p_r. }[/math]
• If R is a commutative ring, [math]\displaystyle{ R^r\langle a_1, ..., a_r\rangle }[/math] is the rank-r free R-module generated by basis elements [math]\displaystyle{ a_1, ..., a_r. }[/math] Example: [math]\displaystyle{ \mathbb{Z}^3\langle \mathbf{L}, \mathbf{m}, \mathbf{s} }[/math]
