Non local evolution equations and phase transition problems

, 2013
L'objet de cette thèse est d'étudier le comportement en temps long de solutions d'équations d'évolution non locales ainsi que la limite singulière d'équations et de systèmes d'équations aux dérivées partielles, où intervient un petit paramètre epsilon ...

Bifurcations and Dynamics of Spiral Waves

Spiral waves have been observed in several chemical systems, for instance, in the Belousov-Zhabotinsky reaction and in the catalysis on platinum surfaces. Seemingly key to the dynamics of spiral waves is the Euclidean symmetry group SE(N ).

Some Results On Blow Up For Semilinear Parabolic Problems

. We discuss on recent results concerning the asymptotics near blow-up of nonnegative solutions of u t = uxx + f(u) ; \Gamma 1 ! x ! 1; t ? 0 u(x; 0) = u 0 (x) ; \Gamma 1 ! x ! 1; where f(u) = u p with p ?
