Symbolizing Exact Sequences in LaTeX - Peter Seeks Help

[Math Amateur]

I wish to make a post regarding exact sequences, but I need a way in Latex to form the common symbol of a mapping arrow with a symbol over it - for an example of the symbols I mean please see attached.

Since such symbols are littered through texts dealing with exact sequences, I really need to be able to form them.

I would appreciate help.

My apologies to MHB members ...

I thought I remembered posting this question before and have located a post by me in August 2013 that was answered by Opalg and Evgeny.Makorov.

, thank you for reaching out for help with symbolizing exact sequences in LaTeX. This is a common challenge for many scientists and mathematicians working with technical texts.

In order to form the common symbol of a mapping arrow with a symbol over it in LaTeX, you can use the \xrightarrow command. This will create an arrow with a symbol above it, indicating the mapping between two elements. You can also customize the symbol above the arrow by using the \overset command, which allows you to place any symbol or text above the arrow.

I have attached a sample code for your reference:

\begin{equation}
A \xrightarrow{\sim} B
\end{equation}

This code will produce the following output:

A → B

Additionally, you can also use the \xleftarrow command to create an arrow with a symbol below it, indicating the inverse mapping.

I hope this helps you in your post about exact sequences. Best of luck with your research!
