SUMMARY
The discussion focuses on solving the non-homogeneous partial differential equation (PDE) given by \( u_{t} = ku_{xx} \) with specific boundary conditions \( u_{x}(0, t) = 0 \) and \( u_{x}(L, t) = B \neq 0 \). The participant concludes that no equilibrium solution exists due to the inability to solve \( u_{xx} = 0 \) under the provided boundary conditions. They successfully derived a new linear homogeneous PDE by selecting a reference function \( r(x, t) = c_{1}\frac{x^2}{2} \) and adjusting the solution accordingly, confirming the validity of their method.
