SUMMARY
The discussion focuses on solving a coupled partial differential equation (PDE) system involving complex variables, specifically the equations (r^2 ∇² - 1) X(r,θ,z) + 2 ∂Y/∂θ = 0 and (r^2 ∇² - 1) Y(r,θ,z) - 2 ∂X/∂θ = 0. A proposed solution involves defining Z(r,θ,z) as X(r,θ,z) + i Y(r,θ,z), which simplifies the problem. The user suggests that separation of variables may not work due to the coupling, but using the substitution z = x + iy allows for the reduction of the system to a single equation. The final equation presented is (r^2 ∇² - 1) Z(r,θ,z) - 2i ∂Z/∂θ = 0.
