What does the space $\overline{\mathbb{C}[z]}$ stands for? Does it contain all the analytic functions or there are something else? And what about the closure thing?

    Could it be the polynomials in the variable $\overline{z}$? As in [Antiholomorphic function](http://en.wikipedia.org/wiki/Antiholomorphic_function)?2011-11-21
