# is there an error in this paper ¿¿

http://vixra.org/pdf/0908.0079v1.pdf

see equation (2.21) the reasoning to get this (2.21) goes from page 9 to page 14

should be the inverse of the potential denoted by $x(V)$ proportional to the half-derivative ?

i mean something $$x(V)= C\frac{d^{1/2}}{dV^{1/2}}N(V)$$

instead of the author's claim $$X(V)= A\frac{dN(V)}{dV}$$

here A and C are constants

The reasoning to get to 2.21 starts from page 9. Which step in particular do you think is wrong? – Mew Mar 13 '13 at 10:39
i think it shoudl be the half derivative since the quantiztion conditions inlcude $\sqrt{E_{n}-V(x)}$ – Jose Javier Garcia Mar 13 '13 at 11:03
