Title: Z_2 Gauge Theory and Duality

Abstract: I will review some recent results on the explicit computation of the first-order alpha prime corrections of static, supersymmetric 4- and 5-dimensional stringy black holes. We will use the framework of the Heterotic Superstring effective action and we will study the corrections to entropy of those black holes and we will compare it to the microscopic computations in the literature. We will also show how some singular solutions are regularized by the alpha prime corrections in d=4 giving rise to globally-regular black-hole spacetimes and how to get regular supersymmetric, rotating black holes in 4 dimensions.
