I want to use type an intersection symbol with a vertical line to indicate intersect transversally of submanifolds, like this:

enter image description here

The symbol I looked up on detexify isn't quite what I want (it gives me \usepackage{ amssymb } $$\pitchfork$$). Does anyone know how to get this symbol? Thanks!

  • What's the problem with amssymb? – Bernard May 26 at 18:20
  • @Bernard -- The vertical member in the amssymb \pitchfork cuts off at the bottom of the cap. The vertical line here has a distinct descender. I don't know the difference in meaning, but it may be significant. – barbara beeton May 26 at 18:37
  • @barbarabeeton: when I compile, the vertical line starts nearly at the base line, without any descender w.r.t. the standard \cap. – Bernard May 26 at 18:57

    There's a symbol \mlcp in the stix fonts. Check the comprehensive symbols list (texdoc comprehensive). – barbara beeton May 26 at 19:00

Combining other symbols:

\documentclass{article}
\usepackage{mathtools}

\begin{document}

\[
N_1 \cap\kern-0.7em|\kern0.7em N_2
\]

\end{document}
