Excision of ‘ repulson ’ singularities : a spacetime result and its gauge theory analogue
نویسنده
چکیده
We discuss spacetime singularity resolution in the context of the gravity / gauge correspondence, for brane systems which give rise to gauge theories with eight supercharges and no hypermultiplets. The discussion is aimed at non-experts. Writeup of talk on [1] for proceedings of PASCOS-99 (10 16 Dec 1999, Granlibakken, Lake Tahoe); also relevant to Way Beyond the Standard Models Conference (31 Jan 5 Feb 2000, Aspen, Colorado) and CIAR Gravity and Cosmology Programme Meeting (19 22 Feb 2000, Banff, Canada).

Gauge Theory and the Excision of Repulson Singularities
We study brane configurations that give rise to large-N gauge theories with eight supersymmetries and no hypermultiplets. These configurations include a variety of wrapped, fractional, and stretched branes or strings. The corresponding spacetime geometries which we study have a distinct kind of singularity known as a repulson. We find that this singularity is removed by a distinctive mechanism,...
متن کاملPopulating the swampland : the case of U ( 1 ) 496 and E 8 × U ( 1 ) 248
For d = 10 N = 1 SUGRA coupled to d = 10 N = 1 SYM, anomaly cancellation places severe constraints on the allowed gauge groups. Besides the ones known to appear in string theory, only U(1) and E8 × U(1) are allowed. There are no known theories of quantum gravity that reduce in some limit to these two last supergravity theories, and in this note I present some evidence that those quantum theorie...
متن کاملBig Bang Models in String Theory
These proceedings are based on lectures delivered at the “RTN Winter School on Strings, Supergravity and Gauge Theories”, CERN, January 16 January 20, 2006. The school was mainly aimed at Ph.D. students and young postdocs. The lectures start with a brief introduction to spacetime singularities and the string theory resolution of certain static singularities. Then they discuss attempts to resolv...
متن کاملQuantum Probes of Repulsive Singularities in N = 2 Supergravity
Repulsive singularities (“repulsons”) in extended supergravity theories are investigated. These repulsive singularities are related to attractive singularities (“black holes”) in moduli space of extended supergravity vacua. In order to study these repulsive singularities a scalar test-particle in the background of a repulson is investigated. It is shown, using a partial wave expansion, that the...
متن کاملQuantum Group Gauge Theory on Classical Spaces
We study the quantum group gauge theory developed elsewhere in the limit when the base space (spacetime) is a classical space rather than a general quantum space. We show that this limit of the theory for gauge quantum group Uq(g) is isomorphic to usual gauge theory with Lie algebra g. Thus a new kind of gauge theory is not obtained in this way, although we do find some differences in the coupl...
