As consequence we prove that the bounded weak solution becomes instantaneously a continuous function even if the initial datum is merely a bounded function.engjournal articlehttp://inderscience.metapress.com/content/k376h50312414g61/fulltext.pdfhttp://inderscience.metapress.com/restricted access519.9Gradient estimatesquasilinear Fisher-KPP type equationsregularising effectsspatial uniformation.Ecuaciones diferenciales1202.07 Ecuaciones en Diferencias
