In a cylindrical symmetry domain ## \Phi(r,z,\alpha)=\Phi(r,z) ##. Does anyone can point me what can be found in literature to solve, even with an approximate approach, this equation?(adsbygoogle = window.adsbygoogle || []).push({});

[tex] \nabla^2 \Phi(r,z)=-\frac{q}{\epsilon} \exp(-\frac{\Phi(r,z)-V}{V_t}) [/tex]

Where ## q, \epsilon, V ## and ## V_t ## are some (very well known) constants.

Thank you in advance.
