报告摘要
Taylor expansion and Fourier expansion have been widely used to represent functions. A natural question is whether there is some analog for nonlinear dynamic systems. In this talk, we consider Carlemen linearization and Carleman-Fourier linearization of nonlinear dynamical systems and show that the primary block of the finite-section approach has exponential convergence to the solution of the original dynamical system.
