Stringy domain walls of N=1, D=4 supergravity Original Research Article

We examine domain wall solutions of N=1, D=4 supergravity which preserve half of the supersymmetry and arise from Euclidean M2-brane instantons on M5-branes wrapping associative 3-cycles of G2-holonomy manifolds. We also investigate composite solutions which break an additional half of the supersymmetry.
