Unformatted text preview: 1. Let the vector U be deﬁned as
Then the equation can be written as Ut = AUx + BUy
−1 0 B= −1 0
1 The eigenvalues of A are
or λ2 + 1 = 0
λ = ±i So the system behaves like elliptic in the x, t space
The eigenvalues of B are
or λ2 − 1 = 0
λ = ±1
So the system behaves like hyperbolic in the y, t space 220 ...
