The authors study the Lipschitz algebras \(L^p(X,\alpha)\) and \(\text{lip}(X,\alpha)\) for a compact subset \(X\in \mathbb{C}^n.\) They investigate the maximal ideal spaces for subalgebras of these algebras, generated by rational functions or by functions analytic in the interior of \(X.\) Approximation by rational functions is studied also.
