In this paper, we present a detailed analysis of first-order perturbations the Kerr metric in slow-rotation limit. We perform calculation by perturbing Schwarzschild plus up to second-order corrections spin Regge-Wheeler gauge. The apparent coupling between different angular momentum axial-led and polar-led modes can be removed suitably combining perturbation equations projecting them onto spin...

The exact black hole solution of 2D closed string theory has, as any other maximally extended Schwarzschild-like geometry, two asymptotically flat spacetime domains. One can get rid of the second domain by gauging the discrete symmetry on the SL(2,R)/U(1) coset that interchanges the two asymptotic domains and preserves the Kruskal time orientation everywhere in the Kruskal plane. Here it is sho...

on the basis of the steady-state two-dimensional theory of thermoelasticity, stress field around various holes in infinite isotropic plate is discussed. the plate is subjected to uniform heat flux and thermal insulated condition along the hole boundary is assumed. by using the complex potential functions and by applying the conformal mapping and solving the integral equations, the effect of blu...

Indications of the surgical management of macular hole are based on the presence of a fullthickness defect (stage 2 or higher). Once this defect has developed, the potential for spontaneous resolution is low. Since the initial report by Kelly NE, the surgical technique of idiopathic macular hole has been improved (Kelly & Wendel, 1991). Currently, the most standard surgical technique for the tr...

We use a new approach to the UV behavior of quantum general relativity, together with some recent results from the phenomenological asymptotic safety analysis of the theory, to discuss the final state of the Hawking radiation for an originally very massive black hole solution of Einstein's theory. We find that, after the black hole evaporates to the Planck mass size, its horizon is obviated by ...
