Ahmad GhodsiEhsan HatefiRecently a new four-dimensional nonrelativistic renormalizable theory of gravity was proposed by Ho\ifmmode \check{r}\else \v{r}\fi{}ava. In this paper we have found different near horizon geometries in Ho\ifmmode \check{r}\else \v{r}\fi{}ava gravity. We find the rotating solutions in a special range of parameters of the theory. This range allows us to include up to six derivative terms in the equations of motion. We have found our solutions as perturbed solutions over spherical symmetric background with small rotating parameter.

We observe that the N3 entropy behavior of near-extremal M5 branes can be reproduced from SYM side with the role of Myersʼ terms. We start by generalizing the Klebanov–Tseytlin (KT) supergravity solution that displays the N3 entropy behavior. The new feature of the general solution is visibility of the “internal” degrees of the M5 branes, i.e., the M0 branes and the M2 branes. With the rationale provided by the supergravity analysis, we consider a D0 brane quantum mechanical setup with Myersʼ terms. Using localization technique, we show that the leading N3 behavior of the free energy comes from the “classical contribution” with the rest subleading

Ehsan HatefiWe calculate in detail the disk level S-matrix element of one Ramond-Ramond field and three gauge field vertex operators in the world volume of BPS branes, to find four gauge field couplings to all orders of α′ up to on-shell ambiguity. Then using these infinite couplings we find that the massless pole of the field theory amplitude is exactly equal to the massless pole S-matrix element of this amplitude for the p = n case to all orders of α′. Finally we show that the infinite massless poles and the contact terms of this amplitude for the p = n + 2 case can be reproduced by the Born-Infeld action and the Wess-Zumino actions, and by their higher derivative corrections.
