half the first Betti number of $\Sigma$
$\displaystyle \frac{1}{2}\dim H^1(\Sigma\,;\mathbb{Q})\quad,$

If i click on Betti number is get that the homology group
is denoted by
H_{1}(\Sigma\,;\mathbb{Q})

can you change yours to match?

Also, PM lacks any definition of surface. Your entry defines it
but does not have in the defines list. can it be added?
Actually i would perfer a totally separate entry for just
