The general expression of the counterterms and the boundary stress tensor is presented for spacetimes of dimension $d\leq 9$. We apply this tehnique for several different types of black objects. Apart from static and rotating black holes, we consider also Einstein-Gauss-Bonnet black string solutions with negative cosmological constant.27 pages, 6 figures, references added, discussion extendedGeneral Relativity and Quantum CosmologyHigh Energy Physics - Theorytext
