Springer for example uses capital bold Z, I, Q, R, C, not blackboard versions in most of their books whereas Cambridge University press seems to go for Blackboard bold. On the other hand "Wolfram" (tspfka "Mathematica") seems to not only use the uppercase blackboard bold for Reals, Integers etc but also use lowercase blackboard bold for i, e, c_x (arbitrary constants) etc. Which is just annoying. |
