I'm trying to write the "power of a set" in LaTeX, but I don't think that the usual ways to do it look like the handwritten letter (I usually write it as \mathcal{P}, but would like to find another way). Someone answered here, in another context, with an option I would like to use: \euscr{P}, but for some reason I can't quite understand, it doesn't work for me, and looks exactly like \mathcal{P}. Can someone help me to make this work? I think the problem is somewhere in my preamble, maybe conflicting packages? Here is a minimal (non)working example:

    \usepackage[left=2.1 cm,top=2.3 cm,right=2.3 cm,bottom=2.5cm]{geometry} 
    \let\euscr\mathscr \let\mathscr\relax
    \title{\textbf{Chapter I: Differentiable Manifolds}}
    If $\{A_i\}_{i\in I}\subseteq\euscr{P}(M_1)$, where $\mathcal{P}(M_1)$ refers to the power set of $M_1$, then:
    \[F\bigg(\bigcup_{i\in I}A_i\bigg)=\bigcup_{i\in I}F(A_i)\hspace*{0.7cm}\wedge\hspace*{0.7cm}F\bigg(\bigcap_{i\in I}A_i\bigg)=\bigcap_{i\in I}F(A_i)\]

  • Sorry, but I'm not sure about what you mean by that... My code does compile in my latex version... Feb 6 '17 at 18:29
  • you should never load epsfig at all but why the option in \usepackage[dvips]{epsfig} are you using latex+dvips rather than pdflatex? Feb 6 '17 at 18:30
  • A MWE is not only compilable, it is the smallest amount of code required to show your problem, so that we can help you without having to dig in tons of lines of code.

  • Yes, when I compile I run latex, dvips and ps2pdf. I'm not an expert, just found that this worked at stuck with it. However, I'm really puzzled now because the minimal example I posted does work as I want it to... Maybe it doesn't if I try to use too many alphabets? I'm really confused... Feb 6 '17 at 18:32

The commands work correctly, You do not say what you expect.

If I cut your example to a more reasonable size then.

enter image description here

\let\euscr\mathscr \let\mathscr\relax

So all the P work, only you can decide which you want.

  • Yes, your example works, but I don't understand why. I mean, when I compile my entire document, the second and third "Ps" you write look exactly the same, like the third. Do you have any idea why this could be happening? Am I maybe using too many alphabets? However, I'm not getting the "too many alphabets" error... Feb 6 '17 at 18:38
  • Oh, I'm sorry, I made a mistake. I actually was getting the "too many alphabets" error in my bigger code, but missed it, and that's why it wasn't showing the pdf right. Thank you for your answer! Feb 6 '17 at 18:45
