We describe the spatial and temporal organization of spiral and scroll waves in spherical shells of different sizes and solid spheres. We present simulation results for the evolution of the dynamics and clustering of spiral waves as a function of the excitability of the medium. The excitability, topology, and size of the domain places restrictions on how single and multiarmed spiral waves are organized in space. The results in spherical geometries are compared with those in planar two… 
Evolution of Spiral Waves in Excitable Systems
Spiral waves, whose rotation center can be regarded as a point defect, widely exist in various two-dimensional excitable systems. In this paper, by making use of Duan's topological current theory, we
Ginzburg--Landau Patterns in Circular and Spherical Geometries: Vortices, Spirals, and Attractors
This paper consists of three results on pattern formation of Ginzburg–Landau marmed vortex solutions and spiral waves in circular and spherical geometries. First, we completely describe the global
Spiral waves on the sphere for an alloy electrodeposition model
This study extends the results on pattern formation in [27] to include investigations on the spiral wave phenomenology and shows that spiral waves emerge because of the interplay between two specific model parameters: one regulating the oscillatory dynamics in the kinetics and the other one related to the domain size.
Ginzburg-Landau patterns in circular and spherical geometries: vortices, attractors and spirals.
We prove that each equilibrium of the Ginzburg-Landau equation restricted to the invariant subspace of $m$-armed vortex solutions is hyperbolic, that is, its associated linearized operator possesses
Spherical topology in cardiac simulations
It is shown how the choice of biperiodic boundary conditions sustains fibrillation for a longer duration than no‐flux boundary conditions for a given area, and so is commonly invoked, leading to a boundary condition artifact that may complicate the analysis of defibrillation efficacy.

Multiscale Interactions in a 3D Model of the Contracting Ventricle
The results show that the multiscale ventricle model is capable of simulating mechanical contraction, pressure generation and load interactions as well as demonstrating the individual contribution of each ion current.
Splitting-based schemes for numerical solution of nonlinear diffusion equations on a sphere
An advanced study of the recently developed method for the numerical solution of nonlinear diffusion equations on a sphere, which shows that the competition of the three basic mechanisms-the nonlinear interaction, forcing and dissipation-can generate wave solutions that are subjected to the alternating influence of the processes of self-organisation and self-destruction.
Spiral Waves in a Lattice Array of Josephson Junction Chaotic Oscillators with Flux Effects
Josephson junction devices play a significant role in various physical nonlinear systems because of their complex characteristics. Chaotic phenomenon in various types of Josephson junction devices
A guide to modelling cardiac electrical activity in anatomically detailed ventricles.
The aim of this methodological article is to survey recent developments in integrative modelling of electrical activity in the ventricles of the heart, and to provide a practical guide to the resources and tools that are available for work in this exciting and challenging area.


Topological constraints on spiral wave dynamics in spherical geometries with inhomogeneous excitability.
It is shown that heterogeneity and geometry are responsible for the formation of various spiral-wave attractors, in particular pairs of spirals in which one spiral acts as a source and a second as a sink--the latter similar to an antispiral.
The dynamics of three-dimensional scroll waves in excitable media
Abstract We investigate the motion of the central filament of a scroll wave in excitable medium. We assume that two-dimensional spiral solutions are known and use these solutions to produce slowly
Scroll waves in spherical shell geometries.
The evolution of scroll waves in excitable media with spherical shell geometries is studied as a function of shell thickness and outer radius. The motion of scroll wave filaments that are the locii
Dynamics of spiral waves in excitable media with local time-periodic modulation
Abstract The propagation of spiral waves in excitable media with locally inhomogeneous time-periodic modulations is studied numerically, and it is shown that the size of the local inhomogeneity and
Spiral wave behaviors in an excitable reaction-diffusion system on a sphere

Kinematics of spiral waves on nonuniformly curved surfaces
Abstract The evolution of spiral waves in a two-dimensional excitable medium with nonuniform curvature is considered. Using an analytical approach based on approximate kinematical relations, we find
Chemical waves on spherical surfaces
THE concentric-circular and spiral patterns exhibited by the Belousov–Zhabotinsky (BZ) reaction in thin films of solution are representative of spatiotemporal behaviour in a two-dimensional, planar
Spiral wave generation in heterogeneous excitable media.
As the coupling in a heterogeneous excitable medium is reduced, three different types of behavior are encountered: plane waves propagate without breaking up, plane waves break up into spiral waves,
Wave Propagation in Excitable Media with Randomly Distributed Obstacles
It is found that increasing the number of obstacles decreases the conduction velocity of plane waves and decreases the effective diffusion coefficient in the eikonal curvature equation, and the presence of obstacles also increases the inducibility of wave breaks and spiral waves in 2D and 3D excitable media.
Stable spiral structures and their interaction in two-dimensional excitable media.
A system with high initial vortex concentration evolves according to the described reactions and exhibits three levels of self-organization, which led to formation and domination of persistent three-armed spirals.
