Fluctuation-Dissipation relations from a modern perspective

MS Gomes-Filho, L Lapas, E Gudowska-Nowak… - arXiv preprint arXiv …, 2023 - arxiv.org
In this review, we scrutinize historical and modern results on the linear response of dynamic
systems to external perturbations and the celebrated relationship between fluctuations and …

Nonlinear self-organized population dynamics induced by external selective nonlocal processes

OT Aranda, ALA Penna, FA Oliveira - Communications in Nonlinear …, 2021 - Elsevier
Self-organization evolution of a population is studied considering generalized reaction-
diffusion equations. We proposed a model based on non-local operators that has several of …

Analytical and numerical solutions of the Riccati equation using the method of variation of parameters. Application to population dynamics

O Tumbarell Aranda… - Journal of …, 2020 - asmedigitalcollection.asme.org
This work presents new approximate analytical solutions for the Riccati equation (RE)
resulting from the application of the method of variation of parameters. The original equation …

Nonlocal pattern formation effects in evolutionary population dynamics

OT Aranda, ALA Penna, FA Oliveira - Physica A: Statistical Mechanics and …, 2021 - Elsevier
In this work, we derive a deterministic equation for a generalized nonlocal population
dynamics that depends fundamentally on two lengths parameters (α, β). We associate these …

Single-species fragmentation: The role of density-dependent feedback

V Dornelas, EH Colombo, C Anteneodo - Physical Review E, 2019 - APS
Internal feedback is commonly present in biological populations and can play a crucial role
in the emergence of collective behavior. To describe the temporal evolution of the …

Pattern formation in the doubly-nonlocal Fisher-KPP equation

C Kuehn, P Tkachov - arXiv preprint arXiv:1805.02116, 2018 - arxiv.org
We study the existence, bifurcations, and stability of stationary solutions for the doubly-
nonlocal Fisher-KPP equation. We prove using Lyapunov-Schmidt reduction that under …

Stationary and dynamical critical behavior of the three-dimensional Diffusive Epidemic Process

C Argolo, V Tenório, ML Lyra - Physica A: Statistical Mechanics and its …, 2019 - Elsevier
We investigate the critical behavior of a stochastic lattice model describing the hopping of
two species that undergo reactions B→ A and A+ B→ 2 B. We simulate the model defined on …
