The entropy function for five-dimensional supersymmetric black rings, which are solutions of U(1)(3) minimal supergravity, is calculated via both on-shell and off-shell formalism. We find that at the tree level, the entropy function obtained from both perspectives can reproduce the Bekenstein-Hawking entropy. We also compute the higher order corrections to the entropy arising form five-dimensional Gauss-Bonnet term as well as supersymmetric R-2 completion respectively and compare the results… 

Near the horizon of 5D black rings

For the five dimensional = 2 black rings, we study the supersymmetry enhancement and identify the global supergroup of the near horizon geometry. We show that the global part of the supergroup is
