Rigidity definition

Rigidity means that “nearby” structures (morphisms, derivations, cocycles, etc.) are mutually equivalent, whatever that might mean;

Rigidity for a given dynamical system means that every nearby dynamical system (usually in the C1-topology on maps) is topologically equivalent to the initial system. One cannot expect the conjugacy to be differentiable, because there are linear invariants associated to periodic points which are not invariant under C1-perturbation. Smale’s paper [59] laid the foundations for this theory some 25 years ago, and the subject has seen remarkable developments since then, especially for hyperbolic dynamical systems. For the the non-hyperbolic case, the subject is still in development, as pointed out in the opening talk by

Rigidity means the inability to change one's beliefs even when they have been discredited. It leads to a simplified, often false understanding of reality;

  • Ambulatory long-term electromyography can quantify tremor reliably while the patient is at home engaged in normal daily activity.23 Rigidity can be quantified in a laboratory set-up using torque displacement.24 Alternatively, rigidity can be measured using small sensors that measure force and displacement during actual clinical testing and compute the impedance of the elbow.25 The value of measuring rigidity is questioned, because rigidity itself may not be the clinically most disabling symptom.
