Perturbation of well-posedness and layer potentials for higher-order elliptic systems with rough coefficients
Ariel Barton
In this paper we study boundary value problems for higher order elliptic differential operators in divergence form. We consider the two closely related topics of inhomogeneous prob…

Trace and extension theorems relating Besov spaces to weighted averaged Sobolev spaces
Ariel Barton
There are known trace and extension theorems relating functions in a weighted Sobolev space in a domain U to functions in a Besov space on the boundary bU. We extend these theorems…
