Bifurcations of transition states: Morse bifurcations [PDF]
Nonlinearity, 2014 A transition state for a Hamiltonian system is a closed, invariant, oriented, codimension-2 submanifold of an energy-level that can be spanned by two compact codimension-1 surfaces of unidirectional flux whose union, called a dividing surface, locally separates the energy-level into two components and has no local recrossings.

Bifurcation of Nonlinear Equations: II. Dynamic Bifurcation [PDF]
Methods and Applications of Analysis, 2004 [Part 1 appeared ibid., 155--178 (1994; Zbl 1095.47027), see the preceding review.] The authors study dynamic bifurcation when the eigenvalue of the linearized problem has algebraic multiplicity one or two. As in the first part of the work for steady state bifurcations, their key idea is to analyze precisely the effect of the higher-order nondegenerate

Bifurcations of piecewise smooth flows:perspectives, methodologies and open problems [PDF]
, 2012 In this paper, the theory of bifurcations in piecewise smooth flows is critically surveyed. The focus is on results that hold in arbitrarily (but finitely) many dimensions, highlighting significant areas where a detailed understanding is presently ...

The flatness of bifurcations in 3D dendritic trees: an optimal design
Frontiers in Computational Neuroscience, 2012 The geometry of natural branching systems generally reflects functional optimization. A common property is that their bifurcations are planar and that daughter segments don’t turn back in the direction of the parent segment.

Bifurcations analysis of turbulent energy cascade [PDF]
, 2015 This note studies the mechanism of turbulent energy cascade through an opportune bifurcations analysis of the Navier--Stokes equations, and furnishes explanations on the more significant characteristics of the turbulence.

Stochastic Bifurcations and Excitement in the ZS-Model of a Thermochemical Reaction
Mathematics, 2022 The Zeldovich–Semenov model of the continuous stirred tank reactor with parametric random disturbances in temperature is considered. We study a phenomenon of noise-induced transformation of the equilibrium mode into the mixed-mode oscillatory stochastic ...

Automated measurements of retinal bifurcations [PDF]
, 2009 This paper presents an analysis of the bifurcations of retinal vessels. The angles and relative diameters of blood vessels in 230 bifurcations were measured using a new automated procedure, and used to calculate the values of several features with known ...

Small aspect ratio Taylor-Couette flow: onset of a very-low-frequency three-torus state [PDF]
, 2003 The nonlinear dynamics of Taylor-Couette flow in a small aspect ratio annulus (where the length of the cylinders is half of the annular gap between them) is investigated by numerically solving the full three-dimensional Navier-Stokes equations.
