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.

See the post at http://mathhelpboards.com/latex-help-discussion-26/exact-sequences-functions-longright-arrows-6047.htmlMy thanks to these two members once againhttp://mathhelpboards.com/members/evgeny-makarov/!
