ABSTRACT
We consider nonlinear evolution equations of the form () u t − Δ u m = f ( x , u ) , x ∈ Ω , t > 0 u ( x , 0 ) = u 0 ( x ) , x ∈ Ω u ( x , t ) = u 1 ( x , t ) , x ∈ ∂ Ω , t > 0 ; https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003072683/4382fcd0-4153-46e7-888a-e0b6b9eb509e/content/eq1181.tif"/>
