Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Dynamics of a Nutrient-Phytoplankton Model with Random Phytoplankton Mortality
随机浮游植物死亡率 营养-浮游植物 模型动力学
2023/4/28
In this talk, we investigate a stochastic nutrient-phytoplankton model which incorporates the effect of white noise on phytoplankton growth. The global existence and uniqueness of a positive solution,...
Lattice Models of Nonequilibrium Bacterial Dynamics
Lattice Models Nonequilibrium Bacterial Dynamics
2011/3/2
We study a model of self propelled particles exhibiting run-and-tumble dynamics on lattice. This non-Brownian di usion is characterised by a random walk with a nite persistence length between changes...
Prevalent dynamics at the first bifurcation of Henon-like families
Prevalent dynamics Henon-like families
2010/11/23
We study the dynamics of strongly dissipative H\'enon-like maps, around the first bifurcation parameter $a^*$ at which the uniform hyperbolicity is destroyed by the formation of tangencies inside the ...

We show that complete cotangent lifts of vector fields, their decomposition into vertical representative and holonomic part provide a geometrical framework underlying Eulerian equations of continuum ...
Diffusive limit for a quantum linear Boltzmann dynamics

2010/11/17
We study the diffusive behavior for a quantum test particle interacting with a dilute background gas. The model we begin with is a reduced picture for the test particle dynamics given by a quantum lin...

In this paper we introduce a simple model for a financial market characterized by a sin-
gle stock or good and an interplay between two different traders populations, chartists and
fundamentalists, ...
The Stability and Dynamics of Localized Spot Patterns in the Two-Dimensional Gray-Scott Model
matched asymptotic expansions spots self-replication logarithmic expansions eigenvalues,
2010/12/15
The dynamics and stability of multi-spot patterns to the Gray-Scott (GS) reaction-diffusion model in a two-dimensional domain is studied in the singularly perturbed limit of small diffusivity " of one...
Interaction and chaotic dynamics of the classical hydrogen atom in an electromagnetic field
classical hydrogen atom electromagnetic field angular momentum
2010/4/1
Expressions for energy and angular momentum changes of the hydrogen atom due to interaction with the electromagnetic field during the period of the electron motion in the Coulomb field are derived. It...
Anticipation and the Non-linear Dynamics of Meaning-Processing in Social Systems
anticipation social system meaning incursion globalization
2010/4/7
Social order does not exist as a stable phenomenon, but can be considered as "an order of reproduced expectations." When anticipations operate upon one another, they can generate a non-linear dynamics...
