A trio of heteroclinic bifurcations arising from a model of spatially-extended Rock-Paper-Scissors [PDF]

open access: yes, 2019
One of the simplest examples of a robust heteroclinic cycle involves three saddle equilibria: each one is unstable to the next in turn, and connections from one to the next occur within invariant subspaces.

Lyapunov-Schmidt and Centre Manifold reduction methods for nonlocal PDEs modelling animal aggregations [PDF]

open access: yes, 2016
The goal of this paper is to establish the applicability of the Lyapunov–Schmidt reduction and the Centre Manifold Theorem (CMT) for a class of hyperbolic partial differential equation models with nonlocal interaction terms describing the aggregation ...

Analysis of delayed bifurcations in reaction-diffusion systems

open access: yes, 2016
We analyze examples of delayed bifurcations in reaction-diffusion systems in both the weakly and fully nonlinear regimes. The delay effect results as the system passes slowly from a stable to unstable regime, and was previously analyzed in ODEs in [P ...

Spectral continuation study of the temporally periodic solitons of the damped-driven nonlinear Schrödinger equations

open access: yes, 2012
Includes abstract.Includes bibliographical references.In this thesis we develop and employ a spectral continuation algorithm, implemented in AUTO, to study the temporally periodic spatially localised soliton solutions of the driven, damped nonlinear ...

Reduced models for optimal control, shape optimization and inverse problems in haemodynamics

open access: yes, 2013
ECCOMAS PhD AwardInternational audienceDespite the computer resources nowadays available, it is still difficult - and often impossible - to deal with applications and scenarios involving the repeated solution of PDEs on different data settings (many-query

Low-order dynamical modeling and intelligent control of thermo-fluid systems via proper orthogonal decomposition.

open access: yes, 1997
In the present investigation, low-order dynamical models of transitional thermo-fluid systems in complex configurations have been developed. Proper orthogonal decomposition (POD) has been applied to supercritical oscillatory solutions, obtained by ...

Symmetry of generic bifurcations in cubic domains

open access: yes
It is now well known that bifurcation problems arising from elliptic PDEs on finite domains may possess translational symmetries, even though translations cannot leave a finite domain invariant.
