Abstract
We consider domain walls embedded in curved backgrounds as an approximation for braneworld scenarios. We give a large class of new exact solutions, ex austing the possibilities for describing one and two walls for the cases wh ere the curvature of both the hulk and the wall are locally constant. In th e case of two walls, we find solutions where each wall has positive tension . An interesting property of these solutions is that the curvature of the w alls can be much smaller than the tension, leading to a significant cancell ation of the effective cosmological constant, which however is still much l arger than the observational limits. We further discuss some aspects of inf lation in models based on wall solutions. [S0556-2821(99)04122-3].
