Random walks Kleinian groups bifurcation currents
2010/11/11
Let (\rho_\lambda)_{\lambda\in \Lambda} be a holomorphic family of representations of a finitely generated group G into PSL(2,C), parameterized by a complex manifold \Lambda . We define a notion of b...
Comment on "Comment on 'Supersymmetry, PT-symmetry and spectral bifurcation'"
PT-symmetry Supersymmetry sl(2) algebra
2010/11/4
In "Comment on Supersymmetry, PT-symmetry and spectral bifurcation" \cite{BQ1}, Bagchi and Quesne correctly show the presence of a class of states for the complex Scarf-II potential in the unbroken P...
Local Bifurcation-Branching Analysis of Global and "Blow-up" Patterns for a Fourth-Order Thin Film Equation
Thin film equation local bifurcation analysis source-type and blow-up similarity solutions
2010/12/14
Countable families of global-in-time and blow-up similarity sign-changing patterns of the Cauchy problem for the fourth-order thin film equation (TFE–4) ut = −∇ · (|u|n∇u) in RN × R...
On the effect of multiplicative noise in a supercritical pitchfork bifurcation
multiplicative noise supercritical pitchfork bifurcation
2010/4/21
The most important characteristic of {\em multiplicative noise} is that its effects of system's dynamics depends on the recent system's state. Consideration of multiplicative noise on self-referential...
Characterizing mixed mode oscillations shaped by noise and bifurcation structure
mixed mode oscillations underlying dynamical structure extrinsic noise
2010/4/2
Many neuronal systems and models display a certain class of mixed mode oscillations (MMOs) consisting of periods of small amplitude oscillations interspersed with spikes. Various models with different...
Saddle-Node Bifurcation to Jammed State for Quasi-One-Dimensional Counter Chemotactic Flow
Saddle-Node Bifurcation Quasi-One-Dimensional Counter Chemotactic Flow Jammed State
2010/4/1
The transition from a free flow state to a jammed state of counter chemotactic flow of particles in a quasi-one-dimensional path is investigated. One of the characteristic features of counter chemotac...
Stability and Bifurcation Analysis of Coupled Fitzhugh-Nagumo Oscillators
Coupled Fitzhugh-Nagumo Oscillators Hindmarsh-Rose Discriminant Variety Morris-Lecar
2010/4/1
Neurons are the central biological objects in understanding how the brain works. The famous Hodgkin-Huxley model, which describes how action potentials of a neuron are initiated and propagated, consis...
Bifurcation of robust heteroclinic cycles in spherically invariant systems with $\ell =3,4$ mode interaction
robust heteroclinic cycles spherically invariant
2010/4/7
Bifurcation with spherical symmetry and mode interaction is known to produce robust heteroclinic cycles between axisymmetric steady-states. The case of mode interaction with representations of $\SO3$ ...
Periodic orbit analysis at the onset of the unstable dimension variability and at the blowout bifurcation
Periodic orbit analysis blowout bifurcation unstable dimension variability
2010/4/7
Many chaotic dynamical systems of physical interest present a strong form of nonhyperbolicity called unstable dimension variability (UDV), for which the chaotic invariant set contains periodic orbits ...
Bifurcation analysis of a paradigmatic model of monsoon prediction
Bifurcation analysis paradigmatic model monsoon prediction
2009/11/11
Local and global bifurcation structure of the forced Lorenz model in the r-F plane is investigated. The forced Lorenz model is a conceptual model for understanding the influence of the slowly varying ...
Multi-parameter uncertainty analysis of a bifurcation point
Multi-parameter uncertainty analysis bifurcation point
2009/11/9
Parameter uncertainty analysis of climate models has become a standard approach for model validation and testing their sensitivity. Here we present a novel approach that allows one to estimate the rob...
Consequences of entropy bifurcation in non-Maxwellian astrophysical environments
entropy bifurcation non-Maxwellian astrophysical environments
2009/11/2
Non-extensive systems, accounting for long-range interactions and correlations, are fundamentally related to non-Maxwellian distributions where a duality of equilibria appears in two families, the non...
The behavior of outflows resulting from channels cutting through broad continents and emptying into wedgelike oceans, or channels cutting in wedgelike continents and emptying into broad oceans, is exa...
Observations of the Pacific North Equatorial Current Bifurcation at the Philippine Coast
North Equatorial Current Philippine Coast
2008/12/27
Hydrographic surveys were conducted off the Philippine coast in September 1987 and April 1988 as part of the United States/People's Republic of China cooperative research program. These cruises sample...
A highly idealized model for the oceanic haline circulation is studied. Specifically, loops filled with salty water and subjected to either the natural boundary condition, the virtual salt flux condit...
