Is there a calligraphic form for $\exists$ and other logic quantifiers? I tried the approach in this answer but that only gives the usual font for this symbol.

  • What do you mean by ‘calligraphic’? Can you point to some source? – egreg Nov 05 '13 at 18:07
  • I do not have an exact definition. Something on the artistic/elaborate side and other than the plain inverted E. – Maesumi Nov 05 '13 at 18:15
  • If you load graphicx package you could try this: \newcommand\calexists{\rotatebox[origin=c]{180}{$\mathcal{E}$}} but (in my opinion) it does not look very nice with the E in the mathcal font. The A is slightly better. – Thruston Nov 05 '13 at 20:17
  • @Thruston Thanks for the code. I was afraid that would be the only option! How would your code be changed if one were to flip, as in $x\to -x$, instead of rotate by 180? – Maesumi Nov 05 '13 at 20:34
  • \newcommand*{\calexists}{\reflectbox{$\exists$}} –  Nov 05 '13 at 22:36
  • Or sticking with \cal, \newcommand\calexists{\reflectbox{$\mathcal E$}}. But this looks even worse (again in my opinion) because it slants the wrong way. And the curly E just like an odd 3. – Thruston Nov 06 '13 at 10:08
  • @egreg I suppose the fonts at the bottom of this list are the closest to calligraphic. Using the fonts listed in The LaTeX Comprehensive Symbol List, under a variety of math font packages, I could not produce anything different from the ordinary $\exists$. – Maesumi Nov 06 '13 at 10:28
  • @Maesumi I've never seen ‘exists’ other than in the ordinary geometric shape. – egreg Nov 06 '13 at 11:34
