The discussion revolves around determining the maximum yield for a steady state solution in a differential equation context. A steady state solution is defined as a constant solution where the derivative is zero, leading to the equations u(1-u)(1+u) - Eu = 0. The steady state solutions are identified as u*(E) = 0 and u*(E) = sqrt(1 - E). The yield is defined as Y = Eu*(E), which results in Y = E sqrt(1 - E) for the non-zero solution, and to find its maximum, the derivative is set to zero, yielding E* = 2/3 as the point of maximum yield. The maximum yield occurs at E = 2/3, confirming the solution's validity.
