# could we obtain the potential (in one dimension) from the Gutzwiller trace?

to solve and obtain the potential of a 1-D Hamiltonian we must solve an integral equation

$$N(E)= A \int_{0}^{E}\frac{V^{-1}(x)}{\sqrt{E-x}}$$

fro a some constant 'A' , then my question is since the approximated espectral fucntion

$$N(E)= <N(E)>+ \sum_{p.p.o}A_{p}e^{\frac{iS(E)}{\hbar}}+c.c$$

with $<N(E)>$ meaning the WKB approximation (smooth) to the spectra staircase and p.p.o means summation over the periodic orbits with $S(E)= \sqrt{2m} l_{p.o}$ the action over the closed orbits , then can i from the Gutzwiller trace formula recover the potential ? this is my ansatz http://vixra.org/pdf/1301.0078v3.pdf which i think is valid at least for one dimension
