Commutative diagrams
It's a compromise, and it's fiddly, but I've been using Geogebra (free download, java based, analytical-geometry based mathematics graphics tool) to do my commutative diagrams with. Might be worth taking a look. --prime mover 07:39, 8 August 2012 (UTC)


 * Well, as it produces images as well, I think I will opt for Mathematica or TeX, when I get my desktop back from repairs. --Lord_Farin 07:42, 8 August 2012 (UTC)

Symbols for objects
$*$ and $\star$ look too similar, IMO. Suggest either one be replaced by $\circ$, despite what may be in the source book. What say? --prime mover 07:14, 16 August 2012 (UTC)


 * $\circ$ seems a bad idea, but I take your point. Take your pick of $\diamond, \square, \diamondsuit, \Diamond$. --Lord_Farin 07:26, 16 August 2012 (UTC)
 * I wonder whether "$\circledast$" instead of $*$? Maybe a few words suggesting that "$*$ is what you normall see but in the interest of reducing eyestrain, ..." --prime mover 08:53, 16 August 2012 (UTC)


 * 't Is immaterial which symbols are used. That's the point of the generic symbology. Used $\circledast$ as suggested. --Lord_Farin 08:57, 16 August 2012 (UTC)
