Instability analysis of saddle points by a local minimax method
The objective of this work is to develop some tools for local instability analysis of multiple critical points, which can be computationally carried out. The Morse index can be used to measure local instability of a nondegenerate saddle point. However, it is very expensive to compute numerically and is ineffective for degenerate critical points. A local (weak) linking index can also be defined ...
متن کاملA Novel Indicator to Predict the Onset of Instability of a Gravitational Flow on a Slope
In order to present a quantitative indicator for the onset of instability, in this paper, the critical points of a stratified gravitational flow on a slope are found and analyzed. These points are obtained by means of the solution of the two-dimensional Navier-Stokes equations via the standard Arakawa-C finite-difference method. Results show that in the marginal Richardson numbers, the critical...
متن کاملOn Finding Multiple Solutions to a Singularly Perturbed Neumann Problem
In this paper, in order to numerically solve for multiple positive solutions to a singularly perturbed Neumann boundary value problem in mathematical biology and other applications, a local minimax method is modified with new local mesh refinement and other strategies. Algorithm convergence and other related properties are verified. Motivated by the numerical algorithm and convinced by the nume...
متن کاملComputational Theory and Methods for Finding Multiple Critical Points
Let H be a Hilbert space and J ∈ C(H, ). Denote δJ its Frechet derivative and J ′ its gradient. The objective of this research is to develop computational theory and methods for finding multiple critical points, i.e., solutions to the Euler-Lagrange equation J (u) = 0. A critical point u is nondegenerate if J (u) is invertible. Otherwise u is degenerate. The first candidates for a critical poin...
متن کاملWhen the Morse index is infinite
Let f be a smooth Morse function on an infinite dimensional separable Hilbert manifold, all of whose critical points have infinite Morse index and co-index. For any critical point x choose an integer a(x) arbitrarily. Then there exists a Riemannian structure on M such that the corresponding gradient flow of f has the following property: for any pair of critical points x, y, the unstable manifol...
