On the fusion problem for degenerate elliptic equations II

Let F be a relatively closed subset of a Euclidean domain Ω . We investigate when solutions u to certain elliptic equations on Ω F are restrictions of solutions on all of Ω . Specifically, we show that if F is not too large, and u has a suitable decay rate near F , then u can be so extended.

Harmonic spaces associated with adjoints of linear elliptic operators

Similarity:

Let L be an elliptic linear operator in a domain in R n . We imposse only weak regularity conditions on the coefficients. Then the adjoint L * exists in the sense of distributions, and we start by deducing a regularity theorem for distribution solutions of equations of type L * u = given distribution. We then apply to L * R.M. Hervé’s theory of adjoint harmonic spaces. Some other properties of L * are also studied. The results generalize earlier work of the author.

Generating singularities of solutions of quasilinear elliptic equations using Wolff’s potential

Similarity:

We consider a quasilinear elliptic problem whose left-hand side is a Leray-Lions operator of p -Laplacian type. If p < γ < N and the right-hand side is a Radon measure with singularity of order γ at x 0 Ω , then any supersolution in W l o c 1 , p ( Ω ) has singularity of order at least ( γ - p ) ( p - 1 ) at x 0 . In the proof we exploit a pointwise estimate of 𝒜 -superharmonic solutions, due to Kilpeläinen and Malý, which involves Wolff’s potential of Radon’s measure.
