Abstract
Arakeljan's Theorem provides conditions on a relatively closed subset of a domain , such that any continuous function that is analytic in , can be approximated by analytic functions defined on . In this paper we will extend Arakeljan's theorem by adding the extra requirement that the analytic functions that approximate may also be chosen to be bounded on a closed set In \cite{RU} the same problem has been considered but for the specific case that . In this paper we will extend the result in \cite{RU} and show that is true for an arbitrary , provided that and satisfy certain topological condition in . Additionally, we will show that the result holds always true when is simply connected.
