These objects generalize hyperbolic fixed points and are ubiquitous in dynamical systems. First, … Web11 de nov. de 2014 · A normally hyperbolic subset S ⊂ C 0 is called attracting if all eigenvalues of $(\mbox{ D}_{x}f)(p, 0)$ have negative real part for p ∈ S; similarly, S is called repelling if all eigenvalues have positive real part. If S is normally hyperbolic and neither attracting nor repelling, it is of saddle type. potato growers canterbury
