Hello,
Lyx offers mathbb
But il looks like that it does not belong to the package
bbold
seems this package is not installed.
My problem is that the package bbold gives me the symbol that I want (like
\mathbb{1})
while, that I get by default with lyx is a bizarre symbol.
The thing to note is that \mathbb{} is only for capital letters. You do
get strange symbols if you use it on lower-case letters. \mathbb{},
usually called "blackboard bold" gives a font similar to what we usually
use on a chalkboard to indicate a bold letter, with doubled line
segments. Try \mathbb{R} for example.
