Stratified fiber bundles, Quinn homology and brane stability of hyperbolic orbifolds
Stratified fiber bundles, Quinn homology and brane stability of hyperbolic orbifolds
We revisit the problem of stability of string vacua involving hyperbolic orbifolds using methods from homotopy theory and K-homology.We propose a definition of Type II string theory on such backgrounds that further carry stratified systems of fiber bundles, which generalise the more conventional orbifold and symmetric string backgrounds, together with …
