英文:
Bold italic capital Greek letters in maths
问题
I'm using R and Bookdown. In the html output I'd like to have an inline boldface italic capital Greek letter. I've tried a variety of inputs, for example
...some text $\bm{\varGamma}$ some text...
...some text $\boldsymbol{\varGamma}$ some text...
...some text $\mathbf{\varGamma}$ some text...
This unanswered question asks about boldface Greek, but the suggestion in the comments of using \mathbf works only with \Gamma. I haven't found any questions about italic capital Greek letters.
Edit: the second input line above works, as explained in the accepted answer below. The real problem came from \varGamma which seems to cause trouble with Bookdown's epub output.

boldsymbol 也可以在使用 html_document 时工作，但要注意 bm 和 boldsymbols 之间的区别：
---
output: html_document
---
...一些文本 **粗体**：$\boldsymbol{\varGamma}$ 一些文本... 不粗体：${\varGamma}$.
英文:
boldsymbol also works using html_document, but be aware of difference between bm and boldsymbols:
---
output: html_document
---
...some text **bold**: $\boldsymbol{\varGamma}$ some text... not bold: ${\varGamma}$.

Edit: leaving this here in case it helps someone else although @Julian's answer is better in this case, poor man's bold is a last resort for bold fonts.
尝试使用"贫人加粗"。 $\pmb{\varGamma}$
普通数学伽玛: $\Gamma$
斜体数学伽玛: $\varGamma$
普通粗斜体伽玛不起作用: $\mathbf{\varGamma}$
'贫人加粗' 斜体伽玛起作用: $\pmb{\varGamma}$

Try poor mans bold. $\pmb{\varGamma}$
Regular math gamma: $\Gamma$
Italic math gamma: $\varGamma$
Regular bold italic gamma doesn't work: $\mathbf{\varGamma}$
'Poor Mans Bold' Italic gamma does work: $\pmb{\varGamma}$
