SUMMARY
The discussion focuses on finding a general solution for the logistic ordinary differential equation (ODE) represented as \(\frac{dU}{dx}=A(I-U)U\), where \(A\) and \(U\) are square matrices. The proposed solution \(U=(I+e^{-Ax})^{-1}\) is valid only when \(U\) and \(A\) commute. The general scalar solution is given by \(\frac{E^{Ax}}{E^{Ax} + E^C}\), but complications arise when \(U\) is a function of both \(A\) and the initial condition, leading to non-commutation issues. The discussion also explores diagonalization of \(A\) and the initial condition as a potential approach to simplify the problem.
