Money growth pegging, Taylor rule, status‐seeking behavior and the “spirit of capitalism”

The Manchester School, Volume 92, Issue 4, Page 313-340, July 2024.
Abstract This paper analyzes the impact of “spirit of capitalism” on stationary welfare and stability properties of a one‐sector Ramsey economy, where the demand of money is motivated by a cash‐in‐advance constraint on consumption expenditures. Preferences are defined over consumption and capital stock. There is a monetary authority that follows either

The three‐species problem: Incorporating competitive asymmetry and intransitivity in modern coexistence theory

Ecology Letters, Volume 27, Issue 4, April 2024.
Modern coexistence theory (MCT) typically focuses on two‐species competition or communities with particular symmetry. Here we study the three‐species Lotka–Volterra competition model, including both pairwise coexistence and founder control. We expand MCT by proposing a third quantity beyond niche and fitness differences: cyclic asymmetry, which can ...

Continuation of connecting orbits in 3D-ODEs: (I) Point-to-cycle connections

, 2007
We propose new methods for the numerical continuation of point-to-cycle connecting orbits in 3-dimensional autonomous ODE's using projection boundary conditions.

Heteroclinic cycles emanating from local bifurcations

Manuscripta Mathematica, 1994
The paper deals with a two-parameter system of ordinary differential equations on \(\mathbb{R}^ n\) \((1) : \dot x = f(x, \lambda, \alpha)\), where \(f\) is \(Z_ 2\)-symmetric, i.e. there exists a linear mapping \(g : \mathbb{R}^ n \to \mathbb{R}^ n\) such that \(g^ 2 = I\), \(g \neq I\) and \(gf(x, \lambda, \alpha) = f(gx, \lambda, \alpha)\) for all \(

Intransitivity in plant–soil feedbacks is rare but is associated with multispecies coexistence

Ecology Letters, Volume 27, Issue 3, March 2024.
Plant–soil feedbacks (PSFs) impose similarly strong fitness differences and stabilizing‐destabilizing forces, most often impeding species coexistence. At the community level, PSFs alone do not explain coexistence in species‐rich communities. A topological analysis of the PSF interactions network shows that full intransitivity would be rare in the ...

Bianchi Cosmologies with Anisotropic Matter: Locally Rotationally Symmetric Models

, 2009
The dynamics of cosmological models with isotropic matter sources (perfect fluids) is extensively studied in the literature; in comparison, the dynamics of cosmological models with anisotropic matter sources is not.

Combining intransitive and higher‐order effects in a coupled oscillator framework: A case study of an ant community

Ecology, Volume 105, Issue 2, February 2024.
Abstract A growing body of literature recognizes that pairwise species interactions are not necessarily an appropriate metaphorical molecule of community ecology. Two examples are intransitive competition and nonlinear higher‐order effects. While these two processes have been discussed extensively, the explicit analysis of how the two of them behave ...

Heteroclinic Chaos, Chaotic Itinerancy and Neutral Attractors in Symmetrical Replicator Equations with Mutations

, 2000
A replicator equation with mutation processes is numerically studied. Without any mutations, two characteristics of the replicator dynamics are known: an exponential divergence of the dominance period, and hierarchical orderings of the attractors.

Relaxation Oscillation in SEIR Epidemic Models with the Intrinsic Growth Rate

Complexity, Volume 2024, Issue 1, 2024.
The periodic oscillation transmission of infectious diseases is widespread, deep understanding of this periodic pattern and exploring the generation mechanism, and identifying the specific factors that lead to such periodic outbreaks, which are of very importanceto predict and control the spread of infectious diseases.

Effect of Noise on Excursions To and Back From Infinity

, 2001
The effect of additive white noise on a model for bursting behavior in large aspect-ratio binary fluid convection is considered. Such bursts are present in systems with nearly square symmetry and are the result of heteroclinic cycles involving infinite ...
