A Note on the dS Swampland Conjecture, Non-BPS branes and K-theory
arXiv:1906.06078 · doi:10.1002/prop.201900068
Abstract
We point out that the de Sitter swampland conjecture would be falsified if classical fluxed Type IIA orientifold vacua with a single non-BPS D7-brane were indeed part of the string theory landscape. In other words, the dS swampland conjecture implies the cancellation of K-theory charges on a compact space.
