In this article, the usefulness of Chebyshev series expansions in one dimension is transferred two the two dimensional setting by an adaptive method which works on bivariate domains. These domains must be smooth transformations of the unit square in two dimensions. Not only the analytical construction, but also the implementation is provided, together with numerical examples and applications.
