    • Approximating travelling waves by equilibria of non-local equations 

      Arrieta, J.M.; López-Fernández, M.; Zuazua, E. (2012-12-31)
      We consider an evolution equation of parabolic type in R having a travelling wave solution. We study the effects on the dynamics of an appropriate change of variables which transforms the equation into a non-local evolution ...
    • On a nonlocal moving frame approximation of traveling waves 

      Arrieta, J.M.; López-Fernández, M.; Zuazua, E. (2011-12-31)
      The profiles of traveling wave solutions of a 1-d reaction-diffusion parabolic equation are transformed into equilibria of a nonlocal equation, by means of an appropriate nonlocal change of variables. In this new formulation ...
