Abstract: | It is proved that, if a sufficiently smooth solution $(u,v)=(u(x,t),v(x,t))$ to the initial value problem associated with the dispersive coupled system
{? t u+?3x u+? x(up vp+1)=0,
? t v+?3x v+?x(up+1vp)=0, x ∈R, t ≥ 0
is supported on a half line at two different instants of time then u ≡ 0, v ≡ 0. |
