A density property for tensor products of gradients of harmonic functions and applications

Cătălin I. Cârstea, Ali Feizmohammadi

We show that tensor products of $k$ gradients of harmonic functions, with $k$ at least three, are dense in $C (Ω)$ , for any bounded domain $Ω$ in dimension 3 or higher. The…

An inverse boundary value problem for certain anisotropic quasilinear elliptic equations

Cătălin I. Cârstea, Ali Feizmohammadi

In this paper we prove uniqueness in the inverse boundary value problem for quasilinear elliptic equations whose linear part is the Laplacian and nonlinear part is the divergence o…

Recovery of coefficients for a weighted p-Laplacian perturbed by a linear second order term

Cătălin I. Cârstea, Manas Kar

This paper considers the inverse boundary value problem for the equation $\nabla \cdot (σ \nabla u + a ∣\nabla u ∣^{p - 2} \nabla u) = 0$ . We give a procedure for the recovery of the coefficie…
