copy-editing . . ..
Hello. I've just done a bunch of routine copy-editing on semi-invariants of quivers, bringing it into line (except that I may have missed a detail here and there) with standard usage conventions from WP:MOS, WP:MOSMATH, and the world at large. For example, I found this:

\begin{array}{ccc} GL(\mathbf{d}) \times \operatorname{Rep}(Q,\mathbf{d}) & \longrightarrow &\operatorname{Rep}(Q,\mathbf{d})\\ \Big((g_i), (V_i, V(\alpha))\Big) & \longmapsto & (V_i,g_{t(\alpha)}\cdot V(\alpha)\cdot g_{s(\alpha)}^{-1} ) \end{array} $$ and changed it to this (using "align" rather than "array"):

\begin{align} GL(\mathbf{d}) \times \operatorname{Rep}(Q,\mathbf{d}) & \longrightarrow \operatorname{Rep}(Q,\mathbf{d})\\ \Big((g_i), (V_i, V(\alpha))\Big) & \longmapsto (V_i,g_{t(\alpha)}\cdot V(\alpha)\cdot g_{s(\alpha)}^{-1} ) \end{align} $$ Also:
 * "displayed" as opposed to "inline" mathematical notation gets indented by an initial colon;
 * to make non-TeX math notation match TeX style as closely as possible, variables are italicized, but digits, punctuation, etc. are not, nor are things like sin, max, det, log, etc.;
 * There were things like Q_0 that I changed to Q0;
 * There were things like "Sato-Kimura" and "Littlewood-Richardson", that I changed to "Sato–Kimura" and "Littlewood–Richardson" (this is codified in WP:MOS);
 * . . . and things like -1 that I changed to −1;
 * Some things like
 * $$ det(A) \, $$
 * I changed to
 * $$ \det(A) \, $$
 * (coded as \det, with a backslash. This not only prevents italicization but also provides proper spacing in expressions like $$\displaystyle a\det b\,$$).  And as with \det, so also with \dim.

. . . and miscellaneous other similar things. Michael Hardy (talk) 18:20, 26 March 2014 (UTC)


 * . . . and now I've changed the title to Semi-invariant of a quiver, in accordance with SINGULAR. Michael Hardy (talk) 17:47, 27 March 2014 (UTC)

Hi Ennesse86, I replaced a jpg of yours with text math, and wanted to bring it to your attention in case you objected for some reason. Cheers, Storkk (talk) 14:33, 7 April 2014 (UTC)
