Approximation in AC(σ)

For a nonempty compact subset σ in the plane, the space A C ( σ ) is the closure of the space of complex polynomials in two real variables under a particular variation norm. In the classical setting, AC [0, 1] contains several other useful dense subsets, such as continuous piecewise linear functions...
