In the present thesis a theo-retical investigation of the electronic structure and quantum transport properties of quantumdots has been performed. In addition to the research performed, the theoretical frameworkfor investigating transport through open and almost isolated quantum dots are reviewed.Thereby it is natural to divide the present contribution in two parts.
