Is it possible to get variant Greek letters (\varepsilon, \varkappa etc) when I declare variables?
This:
e = var('e', latex_name='\epsilon')
works as expected. But when I am trying:
e = var('e', latex_name='\varepsilon')
I am seeing unexpeted "arepsilon" when I do show(e).
I am using Sagemath Cloud.
If you make a raw string you never need two backslashes. If you don't, then you may, depending on what is after a backslash. To make a raw string, prefix it with an r, so in this case do
e = var('e', latex_name=r'\varepsilon')
You'll see this r frequently in the Sage source code for the docstrings of functions...
Sometimes in Sage you need two \ marks. Try this:
e = var('e', latex_name='\\varepsilon')
show(e)
I thought the need for two \ had to do with whether you had a raw text string or not. That doesn't seem to be the case here. Hopefully someone can fill in the details as to why we need two \ marks here and how we know that 2 are needed.
