A novel phase portrait for neuronal excitability. [PDF]
PLoS ONE, 2012 Fifty years ago, FitzHugh introduced a phase portrait that became famous for a twofold reason: it captured in a physiological way the qualitative behavior of Hodgkin-Huxley model and it revealed the power of simple dynamical models to unfold complex ...

Symmetries in Phase Portrait [PDF]
Symmetry, 2020 We construct polynomial dynamical systems x ′ = P ( x ) with symmetries present in the local phase portrait. This point of view on symmetry yields the approaches to ODEs construction being amenable to classical methods of the Spectral Analysis.

Qualitative analysis and solitary wave solutions of the new extended (3+1)-dimensional Sakovich equation in fluid dynamics [PDF]
Scientific ReportsThis article investigates the qualitative behavior and solitary wave solutions of the extended (3+1)-dimensional Sakovich equation from fluid dynamics. By using a traveling wave transformation, the new extended (3+1)-dimensional Sakovich equation can be ...

Phase portraits of Bernoulli quadratic polynomial differential systems
Electronic Journal of Differential Equations, 2020 In this article we study a new class of quadratic polynomial differential systems. We classify all global phase portraits in the Poincare disk of Bernoulli quadratic polynomial differential systems in R^2.

Phase Portraits of Hyperbolic Geometry [PDF]
The Mathematical Intelligencer, 2019 Phase plotting is a useful way of visualising functions on complex space. We reinvent the method in the context of hyperbolic geometry, and we use it to plot functions on various representative surfaces for hyperbolic space, illustrating with direct motions in particular. The reinvention is nontrivial, and we discuss the essential features for ensuring
