Identification of single- and double-well coherence-incoherence patterns by the binary distance matrix
Vagner dos Santos, Matheus Rolim Sales, Sishu Shankar Muni +4
The study of chimera states or, more generally, coherence-incoherence patterns has led to the development of several tools for their identification and characterization. In this wo…
Limit Cycles Appearing from a Generalized Heteroclinic Loop with an Elementary Saddle and a Nilpotent Saddle by Perturbing Piecewise Hamiltonian Systems
Zhou Jin, Zhouchao Wei, Sishu Shankar Muni
In this paper, we study limit cycle bifurcations for a class of general near-Hamiltonian systems near a heteroclinic loop with an elementary saddle and a nilpotent saddle. Firstly,…
Transition from chimera/solitary states to traveling waves
Elena Rybalova, Sishu Muni, Galina Strelkova
We study numerically the spatiotemporal dynamics in a ring network of nonlocally coupled nonlinear oscillators, each represented by a two-dimensional discrete-time model of the cla…
Route to chaos and chimera states in a network of memristive Hindmarsh-Rose neuron model with external excitation
Sishu Shankar Muni, Zeric Tabekoueng Njitacke, Cyrille Feudjio +2
In this paper, we have introduced and investigated the collective behavior of a network of memristive Hindmarsh-Rose (HR) neurons. The proposed model was built considering the memr…
Globally Resonant Homoclinic Tangencies
Sishu Shankar Muni
The attractors of a dynamical system govern its typical long-term behaviour. The presence of many attractors is significant as it means the behaviour is heavily dependent on the in…
On the analysis of a time varying noise-modulated heterogeneous coupled network of Chialvo neurons under the influence of electromagnetic flux
Indranil Ghosh, Sishu Shankar Muni, Hammed Olawale Fatoyinbo
We perform a numerical study on the application of electromagnetic flux on a heterogeneous network of Chialvo neurons represented by a ring-star topology. Heterogeneities are reali…
Dynamical Model of Mild Atherosclerosis: Applied Mathematical Aspects
Debasmita Mukherjee, Sishu Shankar Muni, Hammed Olawale Fatoyinbo
Atherosclerosis is a chronic inflammatory disease occurs due to plaque accumulation in the inner artery wall. In atherosclerotic plaque formation monocytes and macrophages play a s…
Complex dynamics of a heterogeneous network of Hindmarsh-Rose neurons
Zeric Tabekoueng Njitacke, Sishu Shankar Muni, Soumyajit Seth +2
In this contribution, we have considered the collective behavior of the two as well as the network of heterogeneous coupled Hindmarsh Rose (HR) neurons. The heterogeneous models we…
Numerical bifurcation analysis of improved denatured Morris-Lecar neuron model
Hammed Olawale Fatoyinbo, Sishu Shankar Muni, Indranil Ghosh +2
It is well-known that the electrical activities of neurons are induced by a wide variety of external factors. This work considers the effect of electromagnetic induction on improve…
Dynamical effects of electromagnetic flux on Chialvo neuron map: nodal and network behaviors
Sishu Shankar Muni, Hammed Olawale Fatoyinbo, Indranil Ghosh
We consider the dynamical effects of electromagnetic flux on the discrete Chialvo neuron. It is shown that the model can exhibit rich dynamical behaviors such as multistability, fi…
