- 15.3 Apply von Neumann stability to CTBS for the linear advection equation. (a) Show that G = -z Vz2 + 1, where z = ha(l - e-16). Hint: The quadratic formula applies to complex numbers. (b) Based on the results of part (a), show that CTBS is unconditionally linearly unstable. As a hint, multiply the two solutions found in part (a). Use this product to show that one of the two solutions found in part (a) is always greater than or equal to one, while the other is always less than or equal to one.
