Hi,
Trying to insert the following symbols into my latex document, under the relational symbols heading I want join and square supset.
They both have a little b symbol after. What does that mean; how do I insert them into my doc? I tried adding them ignoring the b but it seemed to error and not work.
I've got the small mac install of latex.
Thanks, Adam
They're using meta-LaTeX on you: that is a superscript "b" ($ indicates a short math expression and the caret is the superscript).
What they're indicating is that there is a footnote. It is shown in the "Binary Operation Symbols" section.
$^b$ Not predefined in a format based on {\tt basefont.tex}. Use one of the style options {\tt oldlfont}, {\tt newlfont}, {\tt amsfonts} or {\tt amssymb}.
So, if you are seeing an error, that would indicate to me that you are using a basefont format. Try one of the style options listed in the footnote and see if you have more luck. As explained below,
\usepackage{newlfont}
is worth a try. That should enable symbols such as \Join.
As the footnote on that page explaines, you should use special settings to get these symbols. So for instance, if you add \usepackage{newlfont} to the top of your file, you'll be able to get the symbols, e.g. $\sqsubset$.
My copy of A Guide to LaTeX by Helmut and Kopka says of \sqsupset (amongst others):
"Note: the underlined symbol names [...] are only available in LaTeX 2e if one of the packages latexsym or amsfonts has been loaded."
The book doesn't show \Join in its symbol tables at all, however it lists \bowtie which appears to produce the same symbol, and which has no footnotes or warnings associated with it at all :-)
