General Warped Solutions in 6d Supergravity — •Christoph Lüdeling — DESY Hamburg

Higher dimensional theories with warped geometry offer interesting possibilities to address e.g. the hierarchy problem. In warped geometry, the metric is of the form d s²= W(y_i) ds₄² +γ_ij(y_i)dyⁱ d y^j, where d s₄² is the four-dimensional metric and yⁱ are the additional coordinates . The most famous example of a warped space is the five-dimensional Randall-Sundrum model.

In this talk I will present the general warped solution in six-diemsnional supergravity. The equations of motion are solved, up to an arbitrary holomorphic function. This function determines the warp factor W, and, via its pole structure, the number of branes.
