Abstract

Criteria for approximability of functions by solutions of homogeneous second order elliptic equations (with constant complex coefficients) in the norms of the Whitney C1C^1-spaces on compact sets in R2\mathbb R^2 are obtained in terms of the respective C1C^1-capacities. It is proved that the mentioned C1C^1-capacities are comparable to the classic CC-analytic capacity, and so have a proper geometric measure characterization.
