Counting Schwarzschild and Charged Black Holes
E. Halyo, B. Kol, A. Rajaraman +1
We review the arguments that fundamental string states are in one to one correspondence with black hole states. We demonstrate the power of the assumption by showing that it implie…
Orientifold Points in M Theory
A. Hanany, B. Kol, A. Rajaraman
We identify the lift to M theory of the four types of orientifold points, and show that they involve a chiral fermion on an orbifold fixed circle. From this lift, we compute the nu…
String Webs and 1/4 BPS Monopoles
O. Bergman, B. Kol
We argue for the existence of many new 1/4 BPS states in N=4 SU(N_c) Super-Yang-Mills theory with N_c>=3, by constructing them from supersymmetric string webs whose external string…
Analytic approximations, perturbation methods, and their applications
P. Jaranowski, K. G. Arun, L. Barack +33
The paper summarizes the parallel session B3 {\em Analytic approximations, perturbation methods, and their applications} of the GR18 conference. The talks in the session reported n…
