I’m fairly new to Logseq, and started taking notes with some formulas dealing with matrices and vectors. I try to follow the textbook convention that vectors get lowercase bold letters, like this: $\bold{a}$. But $\bold{\alpha}$, or any other lowercase Greek letter, renders the letter in italics… like a scalar!

I’ve seen LaTeX solutions online that involve importing packages, which doesn’t seem an option with Logseq/KaTeX at the moment.

I guess more than a few Logseq-ers have encountered this problem before. Does anyone have suggestions or workarounds?

Welcome. Try these:

`$\boldsymbol\alpha$`

`$\bm\alpha$`

`$\pmb\alpha$`

`$\textbf{α}$`

Thanks! Do all those work for you? `$\textbf{α}$`

did the trick for me.

The behaviour with combining characters is inconsistent, though. For instance, if I want to put a hat on the letter, `$\hat{\textbf{α}}$`

and `$\hat{\textbf{η}}$`

work, but `$\hat{\textbf{β}}$`

and `$\hat{\textbf{θ}}$`

don’t work.

Their appearance varies like this:

- Katex (the enabling software) complains with message “No character metrics”.
- Seems that hat through
`\textbf`

is available for vowels only. - Here is how it looks with
`\boldsymbol`

,`\bm`

and`\pmb`
