I can't find this symbol used to indicate the disjoint sharp operator.

It's a # inside a circle. Is this symbol available in LaTex? if not, how can I draw it inside a mathematical equation?

You can use a scaled up version of bigcirc and ooalign:

documentclass{article}

usepackage{amsmath,graphicx}



makeatletter

newcommand{makecircled}[2][mathord]{#1{mathpalettemake@circled{#2}}}

newcommand{make@circled}[2]{%

  begingroupm@th

  vphantom{biggercirc{#1}}%

  ooalign{$#1biggercirc{#1}$crhidewidth$#1#2$hidewidthcr}%

  endgroup

}

newcommand{biggercirc}[1]{%

  vcenter{hbox{scalebox{1.4}{$m@th#1bigcirc$}}}%

}

makeatother



newcommand{disjointsharp}{makecircled[mathbin]{#}}



begin{document}



$Adisjointsharp B_{Adisjointsharp B}$



end{document}

I used mathbin but it could be mathrel depending on the meaning.

See https://tex.stackexchange.com/a/22375/4427 for a quick course on ooalign.

  Thanks, I copied your code and it is fine. The only thing I would change is the fact that the circle is bigget than A and B. How can I change its diameter?

A have created your symbol with a combination of packages. Excuse me for the complicated code. Your symbol have the name disj. It is a variable name that you can changed. Here there is my genuine MWE proposal.

documentclass{article}

usepackage{amsmath,amssymb}

usepackage{MnSymbol,scalerel}

newcommand{disj}{mathrel{{bigcircle}mkern-4muraise.3exllap{$scaleobj{.6}{#}$}}}

begin{document}

You can use TikZ to draw a circle node with a # inside. Using DeclareMathOperator from amsmath improves the spacing. The character should be a bit smaller than the current font, which you can do using smaller from the relsize package, to make sure it works in different fontsizes.

MWE:

documentclass{article}

usepackage{amsmath}

usepackage{tikz}

usepackage{relsize}

DeclareMathOperator{chash}{tikz{node[circle,draw,inner sep=0,outer sep=0]{smaller[3]#}}}

begin{document}

$Achash B$



Huge$Achash B$

end{document}
