Approximation in AC(𝜎)
For a nonempty compact subset sigma in the plane, the space AC(sigma) 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 functi...

| 520 | |a For a nonempty compact subset sigma in the plane, the space AC(sigma) 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, C1 functions and Lipschitz functions. In this paper, we examine analogues of these results in this more general setting. | ||
