Multiple bent arrow between same objects

Question

I'm trying to use the tikz-cd package to write the following diagram with multiple bent arrows between the same two objects, with horizontal dots between them.

My tikz-cd skills are not up to par here. My feeble attempt so far is the following

\documentclass{article}
    \usepackage{tikz-cd}
    \begin{document}
    \begin{equation}
    \begin{tikzcd}
    A \arrow[swap]{d} \\
    B \arrow[bend right = 70]{u} \arrow[bend right = 70, draw=none]{u}{\ldots} \arrow[bend right=120]{u}
    \end{tikzcd}
    \end{equation}
\end{document}

Answer 1

There you go:

To add text to an arrow you just have to insert it between "...". To put the text on the other side of the arrow, append a single quote, like this: "..."'.

I also changed a little how you draw the arrow. Instead of increasing the bend angle of bend right (or bend left), you can set the looseness parameter a little higher. It will look much more... loose :).

The code:

\documentclass{article}
\usepackage{tikz-cd}
\begin{document}
\begin{equation}
\begin{tikzcd}
A \arrow[swap]{d} \\
B \arrow[bend right = 70, "\sigma_1", "\ldots"']{u}
  \arrow[bend right = 90, looseness=2, "\sigma_n"']{u}
\end{tikzcd}
\end{equation}
\end{document}
