The discussion focuses on solving the partial differential equation (PDE) au_x + bu_y + cu = 0 using the method of characteristics. This method allows for interpreting the solution as a surface u = u(x,y), where the equation represents the dot product between the normal vector and the tangent plane at a given point. Participants suggest that this topic should be covered in the course material or can be found in standard PDE textbooks. The method involves integrating the equations for the tangent plane to find the solution.
