Let H(G1) be the set of all holomorphic functions on the domain G1. Two domains G1 and G2 are called Hadamard-isomorphic if H(G1) and H(G2) are isomorphic algebras with respect to the Hadamard product. Our main result states that two admissible domains are Hadamard-isomorphic if and only if they are equal.
