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)
