I'd like to improve the following diagram for a pair of adjoint functors:
This is the code:
\documentclass{article}
\usepackage{amsmath,amssymb,tikz-cd}
\begin{document}
\[
\begin{tikzcd}
\mathcal{D}\arrow[r, shift left=.75ex, "G"{name=G}] & \mathcal{C}\arrow[l, shift left=.75ex, "F"{name=F}]
\arrow[phantom, from=F, to=G, "\dashv" rotate=90].
\end{tikzcd}
\]
\end{document}
Is there a standard diagram for a pair of adjoint functors?
\dashv
symbol a bit smaller (?).\dashv
by either\scriptstyle\dashv
or\scriptscriptstyle\dashv
.
