Admitting a direct interaction between the two bosonic sectors of the theory, we analyse the structure of the space-time in the limits of small, respectively large direct interaction coupling constant. For large direct interaction, the global monopole disappears from the system and leaves behind a negative cosmological constant in the bulk such that gravity-localising solutions are possible without the a priori introduction of a bulk cosmological constant.14 pages including 5 eps figuresHigh Energy Physics - TheoryGeneral Relativity and Quantum Cosmologytext
