I am currently struggling to find a way to write :
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.

; the \cdot
symbol can then be repeated twice.
\documentclass{article}
\usepackage{amsmath}
\usepackage{lmodern}
\DeclareMathAlphabet{\mathsfbfsl}{OT1}{\sfdefault}{bx}{sl} % for boldface slanted sans serif
\newcommand{\vct}[1]{\mathbf{#1}}
\newcommand{\tns}[1]{\mathsfbfsl{#1}}
\newcommand{\cddot}{\mathbin{{\cdot}{\cdot}}}
\begin{document}
$\vct{T}=\tns{C}\cddot\vct{E}$
\end{document}
\mathbin{\cdot\cdot}
?
