10 p, 224.3 KB Skeleton for the one-dimensional aggregation equation / Cantero Guardeño, Juan Carlos (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Orobitg i Huguet, Joan (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
For the aggregation equation in R, we consider the evolution of an initial density corresponding to the characteristic function of some set Ω0. We study the limit measure at the blow up time 1 for Ω0 open or compact and we inspect the limit set (skeleton) where this measure is supported.

14 p, 421.0 KB Explicit upper and lower bounds for the traveling wave solutions of Fisher-Kolmogorov type equations / Gasull, Armengol (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Torregrosa, Joan (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Giacomini, Hector (Université de Tours(France). Laboratoire de Mathématiques et Physique Théorique)
It is well-known that the existence of traveling wave solutions for reaction-diffusion partial differential equations can be proved by showing the existence of certain heteroclinic orbits for related autonomous planar differential equations. [...]

16 p, 396.6 KB Explicit traveling waves and invariant algebraic curves / Gasull, Armengol (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Giacomini, Hector (Université de Tours (France). Laboratoire de Mathématiques et Physique Théorique)
We introduce a precise definition of algebraic travelling wave solution of n-th order partial differential equations and prove that the only algebraic travelling waves solutions for the celebrated Fisher-Kolmogorov equation are the ones found in 1979 by Ablowitz and Zeppetella. [...]
