Regularity results for a class of obstacle problems

Michela Eleuteri (2007)

Applications of Mathematics

Similarity:

We prove some optimal regularity results for minimizers of the integral functional f ( x , u , D u ) d x belonging to the class K : = { u W 1 , p ( Ω ) u ψ } , where ψ is a fixed function, under standard growth conditions of p -type, i.e. L - 1 | z | p f ( x , s , z ) L ( 1 + | z | p ) .

Pointwise estimates of nonnegative subsolutions of quasilinear elliptic equations at irregular boundary points

Jan Malý (1996)

Commentationes Mathematicae Universitatis Carolinae

Similarity:

Let u be a weak solution of a quasilinear elliptic equation of the growth p with a measure right hand term μ . We estimate u ( z ) at an interior point z of the domain Ω , or an irregular boundary point z Ω , in terms of a norm of u , a nonlinear potential of μ and the Wiener integral of 𝐑 n Ω . This quantifies the result on necessity of the Wiener criterion.
