【Abstract】

<正>The recent computation of fully nonlinear unstable solutions to turbulent shear flows has created exciting new connections be- tween turbulence and dynamical systems theory.Here we present a number of equilibrium,traveling wave,and periodic orbit solutions to plane Couette flow for Reynolds numbers above the onset of turbulence.The solutions are embedded in the invariant mea-
