I am currently struggling to find a way to write : enter image description here

I know of \cdots and \cdot but the output is one dot and 3 dots but not two. What is a possible solution to my problem?

Thanks in advance.

    \mathbin{\cdot\cdot}? – egreg Jul 9 '19 at 15:33

You can define your own symbol; since it is a binary operation, use \mathbin; the \cdot symbol can then be repeated twice.


\DeclareMathAlphabet{\mathsfbfsl}{OT1}{\sfdefault}{bx}{sl} % for boldface slanted sans serif
