WebBrouwer’s fixed-point theorem states that any continuous transformation of a closed disk (including the boundary) into itself leaves at least one point fixed. The theorem is also true for continuous transformations of the points on a closed interval, in a closed ball, or in abstract higher dimensional sets analogous to the ball. WebMay 30, 2024 · The fixed point is unstable (some perturbations grow exponentially) if at least one of the eigenvalues has a positive real part. Fixed points can be further classified as stable or unstable nodes, unstable saddle points, stable or unstable spiral points, or stable or unstable improper nodes. dance monkey song mp3
