 |
|
i have been attempting to put in an equasion in tensor diagram notation, i am starting off with the Penrose Covariant derivative:
however, it seems as though it is impossible to imput the "(d", "fb[c", "e)b" or "gh]" because it will not let me put ½ of a full bracket along with any other characters unless the entire thing is within brackets "((d)" (or something like that)
is there a way i can imput these?
PS can't there be a easier to reach chart with the formulas on it? i had to go through the help option (the last place i look after checking everywhere it shoul be in he tabs) to find them... just saying |

You can use lbrace and rbrace instead of the quoted braces. I believe the braces created this way are drawn rather than picked from the font. Not as good looking as the font internal braces, but your formula may come out looking cleaner.
| Code: | | 12 nabla_a lbrace %xi^f%lambda^"(d"_"fb[c"D^"e)b"_"gh]" rbrace |
Also, you may want scaling braces, so the top and bottom of the braces align to the top and bottom of the contained formula section. Use the left and right keywords to accomplish that.
| Code: | | 12 nabla_a left lbrace %xi^f%lambda^"(d"_"fb[c"D^"e)b"_"gh]" right rbrace |
Some find that the drawn braces are too slim. You can fix that with the bold modifier. Often we do not want the contained part bolded, so we also need the nbold modifier.
| Code: | | 12 nabla_a bold left lbrace nbold {%xi^f%lambda^"(d"_"fb[c"D^"e)b"_"gh]"} right rbrace |
Try them out to see your options. |
