The paradox of destabilization of a conservative or non-conservative system by small dissipation, or Ziegler's paradox (1952), has stimulated an ever growing interest in the sensitivity of reversible and Hamiltonian systems with respect to dissipative perturbations. Since the last decade it has been widely accepted that dissipation-induced instabilities are closely related to singularities arising on the stability boundary. What is less known is that the first complete explanation of Ziegler's paradox by means of the Whitney umbrella singularity dates back to 1956. We revisit this undeservedly forgotten pioneering result by Oene Bottema that outstripped later findings for about half a century. We discuss subsequent developments of the perturbation analysis of dissipation-induced instabilities and applications over this period, involving structural stability of matrices, Krein collision, Hamilton-Hopf bifurcation, and related bifurcations.

We are glad to see from the remark that the paradoxical influence of small dissipation emphasized in the seminal work by Hans Ziegler of 1952 and resolved in 1956 by Oene Bottema continues to attract an attention of researchers, confirming that our efforts in writing the survey were not useless.The remark states that the work by Bottema is "a study of the singularity in a simple specific case" while the authors of the remark "provided a final step in the qualitative understanding of Ziegler's paradox as a singularity". Note, however, that the "final step" was already taken by Bottema in 1956; since then it was re-iterated independently by a number of researchers.Indeed, we quote from Bottema (1956) where he studies the stability of a general two-degrees-of-freedom non-conservative system with damping and compares its domain of asymptotic stability (A) with the domain of marginal stability in the absence of damping (B) in the space of the coefficients of the characteristic polynomial (a1, a2, a3); he directly points out that a1 and a3 depend on damping:"One could expect B to be a limit of A, so that for a1 → 0, a3 → 0 the set A would continuously tend to B. That is not the case. . . . Here is the discontinuity we mentioned above. It plays a part in questions regarding the stability of equilibrium. The coefficients a1 and a3 depend on the linear damping forces and it is well known that the stability condition may change in a discontinuous way if a very small damping vanishes at all [1]. The phenomenon may be illustrated by a geometrical diagram.[1] Ziegler, Die Stabilitätskriterien der Elastomechanik, Ing. Arch. 20, 49-56 (1952); Bottema, On the stability of the equilibrium of a linear mechanical system, Journal of Appl. Math. Phys. (ZAMP) 6, 97-104 (1955)."The geometrical diagram plotted by Bottema in 1956 is exactly the Whitney umbrella surface, one half of which bounds the domain of asymptotic stability. Bottema, an established geometer, correctly classifies it as a ruled surface and describes in detail its properties in terms of the generators. Therefore, it was Bottema who in 1956 resolved the Ziegler's paradox by discovering the Whitney umbrella singularity on the stability boundary of two-degrees-of freedom non-conservative systems that include Ziegler's pendulum as a particular case.The results of Arnold on singularity theory of 1970s were quickly known in the Western dynamical systems community. For example, already in 1995, in the work [I. Hoveijn and M. Ruijgrok, The stability of parametrically forced coupled oscillators in sum resonance, Z. Angew. Math. Phys. 46, 384-392 (1995)] the Arnold's method of versal deformation of matrix families was used in order to describe the destabilizing effect of damping in a general four dimensional dynamical system in sum resonance with application to rotating shafts. In the space of parameters of the versal deformation, Hoveijn and Ruijgrok found a generic Whitney umbrella singularity from the list of Arnold and plotted the corresponding singular stability threshold....

“…An important field of application where these destabilization phenomena arise is gyroscopic dynamics. Investigation into the stability of equilibria of the Hauger's [7] and Crandall's [6,15] gyropendulums as well as of the Tippe Top [4,13] and the Rising Egg [4] leads to the system of linear equations known as the modified Maxwell-Bloch equations. For the history and a survey of the literature see [11].…”

Abstract. The paradox of destabilization of a conservative or non-conservative system by small dissipation, or Ziegler's paradox (1952), has stimulated an interest in the sensitivity of reversible and Hamiltonian systems with respect to dissipative perturbations. We discuss the motion of a particle in Brouwer's rotating vessel, a typical gyroscopic system, that has an unstable equilibrium caused by internal damping for a wide range of rotation velocities. Using quasi-periodic averagingnormalization by Mathematica, we find that modulation of the rotation frequency in the cases of single-well and saddle equilibria stabilizes the system for a number of combination resonances, thus producing quenching of the unstable motion.
