Abstract
The convective instability induces the phenomenon of spatial sensitivity to the boundary conditions. We introduce a quantity, the “spatial” Lyapunov exponent, to characterize this kind of complex behavior, in nonchaotic but convectively unstable flow systems. Then we establish a relation between this spatial-complexity index and the comoving Lyapunov exponent.Keywords
