  • @ChristianHupfer I have removed that tag (and formatted a bit). OOzyPal Do you mean this blackboard math font? – TeXnician Jun 2 '17 at 14:54

    @TeXnician: I could have removed the tag also, but I wanted to 'annoy' the O.P. ;-) – user31729 Jun 2 '17 at 14:55

    Your Title is very confusing as you show blackboard bold (double struck) R but you ask for a style like \Re which makes a script R not at all like the image that you show. – David Carlisle Jun 2 '17 at 15:05

Very ugly version with \bbtau from package mathbbol and its bbgreekl option. Don't use it ;-)

\documentclass{article}

\usepackage[bbgreekl]{mathbbol}


\begin{document}

$\bbtau$
\end{document}

enter image description here

    interestingly enough Unicode only has the math double struck in latin and arabic, not greek..... So if this was used in publication once could apply to extend Unicode... – David Carlisle Jun 2 '17 at 14:56
  • As you said it is ugly :). Also it does not scale well with the other equations. I will just go with \mathbb{T}. – OOzy Pal Jun 3 '17 at 8:55
  • @OOzyPal: Well, you asked for \tau in black board letters. \mathbb{T} is black board T ;-) – user31729 Jun 3 '17 at 9:06
