Abstract:
We study O() nonlinear -model in -dimensional curved spacetime with negative cosmological constant, and find a new -lump solution with half-integer winding and divergent energy. When the spatial structure of extra-dimensions is determined by this global defect, a black -brane surrounded by the degenerated horizon is formed and its near-horizon geometry is identified as a warp geometry of cigar type.- sigma model: nonlinear
- any-dimensional
- symmetry: O(N)
- space-time
- cosmological constant
- field equations: solution
- membrane model: D-brane
- membrane model: p-brane
- space-time: warped
