Global bifurcation for monotone fronts of elliptic equations

RM Chen, S Walsh, MH Wheeler - Journal of the European …, 2024 - ems.press
We present two results on global continuation of monotone front-type solutions to elliptic
PDEs posed on infinite cylinders. This is done under quite general assumptions, and in …

Toward Computational Morse–Floer Homology: Forcing Results for Connecting Orbits by Computing Relative Indices of Critical Points

JB van den Berg, M Gameiro, JP Lessard… - Foundations of …, 2024 - Springer
To make progress toward better computability of Morse–Floer homology and thus enhance
the applicability of Floer theory, it is essential to have tools to determine the relative index of …

Spatial Hamiltonian identities for nonlocally coupled systems

B Bakker, A Scheel - Forum of Mathematics, Sigma, 2018 - cambridge.org
We consider a broad class of systems of nonlinear integro-differential equations posed on
the real line that arise as Euler–Lagrange equations to energies involving nonlinear …

Large fronts in nonlocally coupled systems using Conley–Floer homology

BH Bakker, JB van den Berg - Annales Henri Poincaré, 2023 - Springer
In this paper, we study travelling front solutions for nonlocal equations of the type∂ tu= N∗ S
(u)+∇ F (u), u (t, x)∈ R d. Here, N∗ denotes a convolution-type operator in the spatial …

[PDF][PDF] Nonlinear waves in local and nonlocal media: a topological approach

BH Bakker - 2019 - research.vu.nl
Most natural phenomena can be described in terms of how various physical quantities
change with time. For example, Verhulst's law of logistic growth states that the rate of change …
