“…The reason for this is that the Kolmogorov system is spatially two dimensional. The Navier-Stokes equations have been widely investigated for sensitivity analysis of chaotic systems, Refs [14,16,20,21,22,23,32,33,49,90,91,92,93,120,121,127], however, to the author's knowledge sensitivity analysis has not been undertaken on the Kolmogorov system. In this chapter the analysis of the adjoint solutions generated by OCS and NV are compared to MSS to aid in the insight as to what features and structures the control term in the NV method should resemble.…”
