This is my first post on this SE so I apologize if my formatting is bad.

Essentially I am trying to reproduce the small black symbol from the following definition in Allen Hatcher's Algebraic Topology:

(This book can also be accessed from his website for free, and this particular image is from page 26.)

I am trying to figure out how to typeset the small black square between the f and the g(s). I tried the following in my preamble

renewcommand{bullet}{tiny$blacksquare$}

but the square bullet produced looks jarring and does not look like a binary operator, i.e. it is not centered and does not have equal spacing between f and g(s).

Would any of you have any suggestions on how to make this particular symbol?

  Ah, ok! Thank you @HenriMenke! That is very helpful information. For now I think I will just have to settle for the "normal" cdot to represent this operation.

You could also go ahead and fake the symbol using a rule.

newcommandsquarebullet[2]{vcenter{hbox{rule{#1}{#2}}}}

begin{document}

$f cdot g_{f cdot g_{f cdot g}}$

This symbol exists in the mathabx font package. Here is a way to use this symbol without having to load the package:

documentclass{article}

DeclareFontFamily{U}{mathb}{hyphencharfont45}

DeclareFontShape{U}{mathb}{m}{n}%

{<-6> mathb5 %

 <6-7> mathb6

 <7-8> mathb7 %

 <8-9> mathb8 %

 <9-10> mathb9 %

 <10-12> mathb10 %

 <12-> mathb12 }%

 {}

DeclareSymbolFont{mathb}{U}{mathb}{m}{n}

DeclareMathSymbol{sqbullet}{mathbin}{mathb}{"0D}



begin{document}



[ f sqbullet g]%
