AdS3 x S3 x S3 x S1 Solutions of Type IIB String Theory
Abstract
We analyse a recently constructed class of local solutions of type IIB supergravity that consist of a warped product of AdS3 with a seven-dimensional internal space. In one duality frame the only other non-vanishing fields are the NS three-form and the dilaton. We analyse in detail how these local solutions can be extended to globally well-defined solutions of type IIB string theory, with the internal space having topology S3 x S3 x S1 and with properly quantised three-form flux.
