Abstract
- We consider a non-local filtration equation of the form u<subscript>t</subscript> = ΔK(u) + λf(u) (∫<subscript>Ω</subscript> f(u) dx)<superscript>-p</superscript> and a porous medium equation, in this case K(u) = u<superscript>m</superscript>, with some boundary and initial data u<subscript>0</subscript>, where 0 < p < 1 and f, f′, f″ > 0. We prove blow-up of solutions for sufficiently large values of the parameter λ > 0 and for any u<subscript>0</subscript> > 0, or for sufficiently large values of u<subscript>0</subscript> > 0 and for any λ > 0.
