The continuum of wood-induced channel bifurcations
Frontiers in Water, 2023 Accumulations of wood in rivers can alter three-dimensional connectivity and facilitate channel bifurcations. Bifurcations divide the flow of water and sediment into secondary channels and are a key component of anastomosing rivers.

Bifurcations of transition states: Morse bifurcations [PDF]
Nonlinearity, 2014 A transition state for a Hamiltonian system is a closed, invariant, oriented, codimension-2 submanifold of an energy-level that can be spanned by two compact codimension-1 surfaces of unidirectional flux whose union, called a dividing surface, locally separates the energy-level into two components and has no local recrossings.

Uniform approximation for period-quadrupling bifurcations. [PDF]
, 1997 . We derive a uniform approximation for semiclassical contributions of periodic orbits to the spectral density which is valid for generic period-quadrupling bifurcations in systems with a mixed phase space.

Simple and complex dynamics in the model of evolution of two populations coupled by migration with non-overlapping generations [PDF]
Известия высших учебных заведений: Прикладная нелинейная динамика, 2022 Purpose is to study the mechanisms leading to genetic divergence (stable genetic differences between two adjacent populations). We considered the following classical model situation. Populations are panmictic with Mendelian rules of inheritance.

Classification of Codimension-1 Singular Bifurcations in Low-Dimensional DAEs
Frontiers in Applied Mathematics and Statistics, 2022 The study of bifurcations of differential-algebraic equations (DAEs) is the topic of interest for many applied sciences, such as electrical engineering, robotics, etc.

Stability Analysis of a Modified Leslie–Gower Predation Model With Weak Allee Effect in the Prey
Frontiers in Applied Mathematics and Statistics, 2022 In this manuscript, we study a Leslie–Gower predator-prey model with a hyperbolic functional response and weak Allee effect. The results reveal that the model supports coexistence and oscillation of both predator and prey populations.

Dynamics of a plant-herbivore model with a chemically-mediated numerical response
Mathematics in Applied Sciences and Engineering, 2021 A system of two ordinary differential equations is proposed to model chemically-mediated interactions between plants and herbivores by incorporating a toxin-modified numerical response.

The Pitchfork Bifurcation [PDF]
International Journal of Bifurcation and Chaos, 2017 We present the development of a new theory of the pitchfork bifurcation, which removes the perspective of the third derivative and a requirement of symmetry.

Bifurcations in the regularized Ericksen bar model [PDF]
, 2008 We consider the regularized Ericksen model of an elastic bar on an elastic foundation on an interval with Dirichlet boundary conditions as a two-parameter bifurcation problem.
