| Popis: | We uncover new non-supersymmetric boundary conditions in 10- and 11-dimensional supergravity whereby spacetime ends on a smeared distribution of D- and M-branes respectively. For example, we find a solution of type IIB supergravity where the AdS$_5\times\mathbb{S}^5$ vacuum ends on an $SO(6)$-invariant distribution of D3-branes. These distributions give a stringy completion of simple models of tensionful end-of-the-world branes considered previously in the literature. However we find that our solutions are all unstable to the fragmentation of the end-of-the-world brane into its constituents. Comment: 9 pages, 5 figures, v2 contains a revised argument for obtaining the correct boundary conditions in type IIB SUGRA |
