“…In the scalar case, Equation (1.5) is just the p-Laplacian. The case of differential forms on the manifold M = R n appears in Section 6.1 of [13] where it is investigated by the method of Hodge dual systems, see also [12,Section 8].…”
ABSTRACT. We study the relation between Sobolev inequalities for differential forms on a Riemannian manifold (M, g) and the L q,p -cohomology of that manifold.The L q,p -cohomology of (M, g) is defined to be the quotient of the space of closed differential forms in L p (M) modulo the exact forms which are exterior differentials of forms in L q (M).

“…The interested reader may wish to take a note of the interpolation lemmas in [1]. In the present paper I will try to elucidate some new advances of Marcinkiewicz interpolation theorem which arise from a study of the nonlinear p-harmonic type PDEs, [12,13,14,16,18,19,20]. The principal result in this paper can be described as follows:…”

Abstract. We study an inverse problem for nonlinear elliptic equations modelled after the p-Laplacian. It is proved that the boundary values of a conductivity coefficient are uniquely determined from boundary measurements given by a nonlinear Dirichletto-Neumann map. The result is constructive and local, and gives a method for determining the coefficient at a boundary point from measurements in a small neighborhood. The proofs work with the nonlinear equation directly instead of being based on linearization.In the complex valued case we employ complex geometrical optics type solutions based on p-harmonic exponentials, while for the real case we use p-harmonic functions first introduced by Wolff.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
