Higher order H{ö}lder approximation by solutions of second order elliptic equations

Grigori Rozenblum, Nikolay Shirokov

For a given second order elliptic operation $\mathcal{L}$ in a domain $\Omega \subset {\mathbb{R}}^{\mathbf{N}}$, $\mathbf{N}$, and a compact set $\mathbf{K}\subset \Omega$, order $\mathbf{N}$-…
