We show that, under a suitable growth condition on the initial datum near the boundary of its support, a finite part of the family of solutions of the discretized problem maintain unchanged its support.engjournal articlehttp://www.rac.es/ficheros/doc/00111.pdfhttp://www.springer.com/restricted access517.9Nonlinear diffusion equationwaiting timenon-diffusion of the supportsemilinear equationsEcuaciones diferenciales1202.07 Ecuaciones en Diferencias
