When I type

$i\tilde{=} j$

the spacing is less than


i.e. the i, \tilde{=}, and j all appear next to each other without space. How can I change it back to normal spacing?

  • You probably want \cong instead of \tilde{=} – egreg Aug 5 '16 at 9:48

The construction \tilde{=} makes an “accent atom”, which is considered just like a letter (“ordinary atom”).

Using $i\mathrel{\tilde{=}}j$ would solve the spacing problem, but the correct symbol is \cong:

$i \cong j$

    @Dr.ManuelKuehner Being one of the world's leading experts on TeX/LaTeX is a tough job, but someone's got to do it. egreg fills those shoes. – Steven B. Segletes Aug 5 '16 at 11:01

    @Dr.ManuelKuehner My first use of \cong was possibly around 1986😏 – egreg Aug 5 '16 at 12:05
