2019年4月11日 · typing ℕ or \BbbN is the same typing \mathbb{N} or \symbb{N} is the same It only remains to discover what's the relationship between the two cases above. Simple: \symbb{N} does \BbbN. Not really by chaining N to Bbb, but something like that (it's more complicated because one can use range=bb to use a different font for blackboard bold letters).

Commands such as \BbbN are a different thing: they are internal commands defined by unicode-math, which maps calls like \mathbb{N} (or \symbb{N}) to \BbbN. It is possible to use them directly, but I'd not recommend doing it, as you lose in flexibility.

2018年10月12日 · In a LaTeX document, I found the definition of a structure as {\cal_A}_0 = (bbbn; 0; s; =) (written as literals appearing in the compiled document, not as source code and / or in math mode). What could the '\bbbn' mean? From the context, something like $\mathhbb {N}$ would be possible, but I am not sure and it could be everything else from the subject computability theory. I cannot ask the author.

2016年2月5日 · Thanks for referencing the table. using "amssymb" I can generate nice blackboard bold letters such as $\mathbb {R}$. But this package produces strange characters for greek letters, as mentioned in my post above. However, if I use "mathbbol", instead of amssymb, it does generate blackboard bold greek letters. But the problem is the letters such as $\mathbb {R}$ are not as nice as before.

I am trying to achieve this with the range feature of unicode-math as per Section 4.1 of its manual : \documentclass{article} \usepackage{fontspec} \usepackage{unicode-math} \setmathfont{texgyrepagella-math.otf} \setmathfont{Asana-Math.otf}[range={\emptyset}] \begin{document} $\emptyset\mathbb N\BbbN$ \end{document}

2016年5月25日 · I noticed this on accident (I actually meant to render \mathbb{N}_0). Take the following example \documentclass{article} \usepackage{amsmath} \usepackage{amssymb} \begin{document} $$\mathbb{N_0}$$ \end{document} The resulting math renders as I would have expected a blackboard N with a subscript blackboard 0. According to detexify, the symbol in question, also from amssymb, is \nvdash. Why does ...

2012年12月9日 · Q&A for users of TeX, LaTeX, ConTeXt, and related typesetting systems

Do ℕ, \mathbb {N}, \BbbN, \symbb {N} effectively differ, and is there a "canonical" specification of the naturals?
