I have included a picture of a maths equation that I need to convert to LaTeX. However I just can't figure out how to convert the first two symbols or figure out what they are/stand for.
The picture is blurry but it looks like calligraphy
\mathitcal
but I know it's not.

\usepackage{mathrsfs}and$\mathscr{N}\!\mathscr{P} \cap \mbox{co} - \mathscr{N}\!\mathscr{P}$(see output). – Werner Mar 08 '16 at 21:48
