Global stability analysis of an age-structured model assessing the impact of Radopholus similis on banana-plantain production
Frank Kemayou, Roger Tagne Wafo, Samuel Bowong
In this paper, we develop and analyse a mathematical model to investigate the interactions between banana and plantain plants and the nematode \textit{Radopholus similis}, a pest s…
The "neighborhood theorem" for the general relativistic characteristic Cauchy problem in higher dimension
Piotr T. Chrusciel, Roger Tagne Wafo, Finnian Gray
We show that the maximal globally hyperbolic solution of the initial-value problem for the higher-dimensional vacuum Einstein equations on two transversally intersecting characteri…
Global Dynamics for a relativistic charged and colliding plasma in presence of a massive scalar field on the Robertson-Walker spacetime
Marcelin Kenmogne Noumo, Norbert Noutchegueme, Roger Tagne Wafo
We consider the coupled Einstein-Maxwell-Boltzmann system with cosmological constant in presence of a massive scalar field. The background metric is that of Friedman-Lemaître-Rober…
Initial value problems for wave equations on manifolds
Christian Baer, Roger Tagne Wafo
We study the global theory of linear wave equations for sections of vector bundles over globally hyperbolic Lorentz manifolds. We introduce spaces of finite energy sections and sho…
On the characteristic initial value problem for nonlinear symmetric hyperbolic systems, including Einstein equations
Aurore Cabet, Piotr T. Chruściel, Roger Tagne Wafo
We consider a characteristic initial value problem for a class of symmetric hyperbolic systems with initial data given on two smooth null intersecting characteristic surfaces. We p…
Solutions of quasi-linear wave equations polyhomogeneous at null infinity in high dimensions
Piotr T. Chruściel, Roger Tagne Wafo
We prove propagation of weighted Sobolev regularity for solutions of the hyperboloidal Cauchy problem for a class of quasi-linear symmetric hyperbolic systems, under structure cond…
