    In that case, to switch to a different branch than the one that follows the direction vi (as defined above) the continuation must be perturbed. The algebraic bifurcation equation gives the necessary direction. One can often also perturb the system and then try to converge parallel to the original branch; typically the second branch is then found.   Dynamical systems can undergo critical transitions where the system suddenly shifts from one stable state to another at a critical threshold called the tipping point. The decrease in recovery rate Cited by:

    The system parameter induces twice a saddle-node bifurcation. The amplitude of the high-frequency force and the fractional-order induce only once a saddle-node bifurcation in the subcritical and the supercritical case, respectively. The system presents a nonlinear response to the low-frequency by: waves on the ocean, sound waves in the air or other media, and electromagnetic waves, of which visible light is a special case. A common feature of these examples is that they all can be described by partial differential equations (PDE). The purpose of these lecture notes is to give an introduction to various kinds of PDE describing Size: 1MB.

Transition bifurcation branches in non-linear water waves by E. F. Toro Download PDF EPUB FB2

The numerical computation of progressive free surface gravity waves on a horizontal bed is addressed. They are regarded as families of bifurcation branches (lambda, A) sub Q of constant discharge Q. Two transition values Q sub 1 and Q sub 2 were numerically determined with corresponding transition bifurcation branches that classify waves into three disjoint branch sets B sub 1, B sub 2 and B sub 3.

Transition bifurcation branches in non‐linear water waves They are regarded as families of bifurcation branches (λ,A)Q of constant discharge Q. Numerically we determine two transition values Q1 and Q2 with corresponding transition bifurcation branches that.

Nonlinear traveling wave type secondary bifurcation branches are computed for plane Poiseuille flow in the search for a physically more relevant transition criterion. These solutions are approximated by truncated Fourier series in streamwise and spanwise direction together with Chebyshev collocation across the channel.

A saddle–node bifurcation is a local bifurcation in which two fixed points (or equilibrium) of a dynamical system collide and annihilate each other. If the phase space is one dimensional, one of the fixed points is unstable (the saddle), while the other is stable (the node).

A Kelvin mode is interpreted as a modification of a Kelvin wave or a boundary wave along a closed boundary, and a mixed Rossby-gravity mode as a modification of an inertial oscillation or a boundary wave along an open boundary. Transition modes appearing in edge and continental-shelf waves, equatorial waves and free oscillations over a sphere are systematically understood by Cited by: 8.

The bifurcation patterns are analysed in some detail from the computed bifurcation diagram, which shows that in B1 bifurcation is to the left and the amplitude A increases as the wavelength λ.

For piecewise-linear maps, the phenomenon that a branch of a one-dimensional unstable manifold of a periodic solution is completely contained in its stable manifold is codimension-two. Unlike codimension-one homoclinic corners, such “subsumed” homoclinic connections can be associated with stable periodic solutions.
