Let D be the unit disc. We denote by C the set of complex numbers and consider the setis endowed with the supremum norm. It is a well known result [20] that there exist holomorphic functions f on D for which the partial sums S n (f ), n = 1, 2, . . . of the Taylor series with center 0 are dense in A(K) for every K ∈ M D . It is also known that the above result fails [23] if we consider the weighted polynomials 2 n S n (f ), n = 1, 2, . . . instead of S n (f ), n = 1, 2, . . . . In the opposite direction, the main result of this work shows that there exist holomorphic functions f on D for which the sequence 2 n S n (f ), n = 1, 2, . . . is dense in A(K) for specific K ∈ M D . In this case the geometry of K plays a crucial role. We also generalize these results on arbitrary simply connected domains.
