Fractional reaction-diffusion problems
(Universidad de Chile, 2014)
This thesis deals with two different problems: in the first one, we study the large-time behavior of solutions of one-dimensional fractional Fisher-KPP reaction diffusion equations, when the initial condition is asymptotically ...
Surface tension driven flow on a thin reaction front
(Pontificia Universidad Católica del Perú, 2017)
Estudo numérico da aplicação do método dos elementos finitos de Galerkin e dos mínimos quadrados na solução da equação da convecção-difusão-reação tridimensionalNumerical study of the application of Galerkin and least squares finite element methods in the solution of the tridimentional convection-diffusion-reaction equation
Towards Fully Computable Error Bounds for the Incompressible Navier-Stokes Equations
We obtain fully computable constant free a posteriori error bouncls on simplicial meshes for: a nonconforming finite element approximations for a Stokes problem and a low-orcler conformingancl low-orcler stabilizecl ...
Mechanisms of localised pattern formation in systems governed by partial differential equations.
This thesis studies the time-independent solutions of systems of partial differential equations given by reaction-diffusion models. The study is motivated by two different contexts: non-linear optics and cellular ...
Global Continuation of Monotone Wavefronts
In this thesis are studied Reaction diffusion equations with a single delay h that have the form(1.1) Ut(t,x) = ?u(t,x) + f(u(t,x),u(t-h,x))where x E Rn, t E R,h > 0 is the delay. Function f satisfies the monostablitycondition: ...
