Talk:Crossing number inequality

Unclear notation

In the section on variations, in the expression

${\frac {f_{d}^{d+2}(\Delta )}{(d+3)^{d+2}f_{d-1}^{d+1}(\Delta )}}$

is $f_{d}^{d+2}(\Delta )$ supposed to be read as a power $(f_{d}(\Delta ))^{d+2}$? Either way, it is not clear. MWinter4 (talk) 17:21, 18 July 2024 (UTC)
