Question: for the system x = x 3 + 2y 3 y = x 3 (1) prove that V (x,y) = ax 2 + by 2

for the system x = x3 + 2y3 y = x3 (1) prove that V (x,y) = ax2+ by2 cannot be used as a Lyapunov function to show stability of the origin for any a and b. [Hint: consider points x = 2, y = for small .

(2) what are values of a and b such that V (x,y) = ax4 + by4 is a Lyapunov function. (3) conclude about the stability of the origin from the Lyapunov function in (2)?
