Title: Limit of Analog Computation Abstract: The goal of this talk is to discuss limit of analog computation. In the first half of this talk, Computability, computational complexity, real number computation and related works in terms of nonlinear dynamical systems are introduced. In the latter half, we show that there exists a dynamical system with PSPACE computational power. Fragility of the dynamical system implies a trade-off between robustness and power in analog computation.
