Numerical Transitivity and Numerical Leo Properties for Lorenz Maps with Applications to Courbage-Nekorkin-Vdovin Neuron Model

Rudrakshala Kavya Sri, Piotr Bartłomiejczyk, Sishu Shankar Muni

This research investigates the dynamic behavior of one dimensional discrete systems using two computational algorithms, the numerical transitivity and the numerical locally eventua…

Bifurcations of mode-locked periodic orbits in three-dimensional maps

Sishu Shankar Muni, Soumitro Banerjee

In this paper, we report the bifurcations of mode-locked periodic orbits occurring in maps of three or higher dimensions. The `torus' is represented by a closed loop in discrete ti…

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,…

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…

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…

Unfolding globally resonant homoclinic tangencies

Sishu Shankar Muni, Robert I. McLachlan, David J. W. Simpson

Global resonance is a mechanism by which a homoclinic tangency of a smooth map can have infinitely many asymptotically stable, single-round periodic solutions. To understand the bi…

Homoclinic tangencies with infinitely many asymptotically stable single-round periodic solutions

S. S. Muni, R. I. McLachlan, D. J. W. Simpson

We consider a homoclinic orbit to a saddle fixed point of an arbitrary map on and study the phenomenon that has an infinite family of asymptotical…
