Phase Equations for Relaxation Oscillators [PDF]
SIAM Journal on Applied Mathematics, 2000 Summary: We use the Malkin theorem [see \textit{I. G. Malkin}, Some problems in nonliner oscillations theory. (Russian) (1956; Zbl 0070.08703)] to derive phase equations for networks of weakly connected relaxation oscillators. We find an explicit formula for the connection functions when the oscillators have one-dimensional slow variables.

Predator–prey systems with small predator's death rate
Electronic Journal of Qualitative Theory of Differential Equations, 2018 The goal of our paper is to study canard relaxation oscillations of predator–prey systems with Holling type II of functional response when the death rate of predator is very small and the conversion rate is uniformly positive.

Two-stroke relaxation oscillators [PDF]
Nonlinearity, 2020 Abstract Two-stroke relaxation oscillations consist of two distinct phases per cycle—one slow and one fast—which distinguishes them from the well-known van der Pol-type ‘four-stroke’ relaxation oscillations. This type of oscillation can be found in singular perturbation problems in

Relaxation Cycles in a Model of Synaptically Interacting Oscillators
Моделирование и анализ информационных систем, 2017 In this paper the mathematical model of a neural network with a ring synaptic interaction elements is considered. The model is a system of scalar nonlinear differential-difference equations, the right parts of which depend on a large parameter. The unknown

Sand dune vegetation-biocrust interaction as a source of spatial heterogeneity
Journal of Hydrology and Hydromechanics, 2022 Vegetation and biocrust play crucial roles in dune stability and mobility, and their interaction can lead to bistability, temporal oscillations, and hysteresis.

Stochastic and chaotic relaxation oscillations [PDF]
Journal of Statistical Physics, 1989 For relaxation oscillators stochastic and chaotic dynamics are investigated. The effect of random perturbations upon the period is computed. For an extended system with additional state variables chaotic behavior can be expected. As an example, the Van der Pol oscillator is changed into a third-order system admitting period doubling and chaos in a ...

Inhibition-based relaxation oscillations emerge in resonator networks [PDF]
, 2019 We investigate the mechanisms responsible for the generation of oscillations in mutually inhibitory cells of non-oscillatory neurons and the transitions from non-relaxation (sinusoidal-like) oscillations to relaxation oscillations. We use a minimal model

A Data-Based Minimal Model of Episodic Inflation Events at Volcanoes
Frontiers in Earth Science, 2022 Space geodetic time series, be they ground-based or space-based, have increased in length and accuracy. These series can now be mined for information on the qualitative dynamics of volcanic systems directly from surface deformation data.

Temperature dependence of relaxation spectra for highly hydrated gluten networks [PDF]
, 2010 In the present investigation, the temperature dependence (0e50 C) of the relaxation spectrum of hydrated gluten was studied using novel numerical algorithms. Tikhonov regularization, in conjunction with the L-curve criterion for optimal calculation of
