Sermutlu, E.2016-02-082016-02-0819980264-9381http://hdl.handle.net/11693/25454We investigate thermodynamical properties of four- and five-dimensional black-hole solutions of toroidally compactified string theory. We find an explicit expression for the first law of black-hole thermodynamics. We calculate the temperature T, angular velocity Ω and the electromagnetic potentials Φi on the horizon using two different methods.EnglishArticle10.1088/0264-9381/15/6/004
