Weird formatting in a smaller created empty set symbol












2















A while back I created my own sort of emptyset symbol because the "not equal" slash didn't line up and it annoyed me. So I defined my own emptyset via DeclareMathOperator{vempty}{{centernot{Circle}}}. However, when I try to use it in a subscript (as demonstrated below), the slash becomes unaligned with the circle. Does anyone know how to remedy this? Here's my MWE:



documentclass[12pt]{letter}
usepackage{amsmath,amssymb,amsthm,centernot,cases}
usepackage{wasysym}

DeclareMathOperator{vempty}{{centernot{Circle}}}
DeclareMathOperator{vempty}{{text{O}}}

begin{document}
Example of difference between emptyset, varnothing, and vempty:
begin{equation*}
neq emptyset quad neq varnothing quad neq vempty
end{equation*}

Example of pathological behavior:
begin{equation*}
int_{varnothing} f dm quad int_{vempty} f dm
end{equation*}
end{document}

          Symbols from wasysym are defined as



          mbox{wasyfamilysymbol{<number>}}


          so they don't change size in subscripts. Add text around it.



          Oh, and it's not an operator, but an ordinary symbol.

          Personal note: I consider varnothing a symbol good for plumbers. Your variation is even uglier. ;-)

          • Is there a way to create a symbol which is more aesthetic and has the same slash angle as neq? I tried, for example, centernot{0}, but the slash was misaligned inside of the zero.
