Analysis of the local robustness of stability for flows
In this paper the problem of measuring the robustness of stability for a perturbed continuous time nonlinear system at a singular xed point is studied. Various stability radii are introduced and their values for the nonlinear system and its linearization are compared. It is shown that they generically coincide. This result may also be used to show generic continuity of linear real stability rad...
متن کاملSemi-supervised Segmentation Based on Non-local Continuous Min-Cut
We propose a semi-supervised image segmentation method that relies on a non-local continuous version of the min-cut algorithm and labels or seeds provided by a user. The segmentation process is performed via energy minimization. The proposed energy is composed of three terms. The first term defines labels or seed points assigned to objects that the user wants to identify and the background. The...
متن کاملOn the Stability of Non-Abelian Semi-local Vortices
We study the stability of non-Abelian semi-local vortices based on an N = 2 supersymmetric H = SU(Nc)×U(1)/ZNc ∼ U(Nc) gauge theory with an arbitrary number of flavors (Nf > Nc) in the fundamental representation, when certain N = 1 mass terms are present, making the vortex solutions no longer BPS-saturated. Local (ANO-like) vortices are found to be stable against fluctuations in the transverse ...
متن کاملLocal stability of Evolutionary Attractors for continuous structured populations
Adaptive dynamics (see [10], [11], [7], [8]) is a branch of evolutionary ecology, that aims at describing the Darwinian evolution of populations along a phenotypic trait, which characterises each individual. This trait as well as the state of the resident population define the survival rate and reproduction rate of the individual. In the asexual case that we consider here, an offspring has exac...
متن کاملCombinatorial Continuous Maximal Flows
Maximum flow (and minimum cut) algorithms have had a strong impact on computer vision. In particular, graph cuts algorithms provide a mechanism for the discrete optimization of an energy functional which has been used in a variety of applications such as image segmentation, stereo, image stitching and texture synthesis. Algorithms based on the classical formulation of maxflow defined on a graph...
