Chaotic inflation on the brane and the swampland criteria
Abstract
In this paper, we show that single-field chaotic inflation on the brane with the potential V =a ϕp is compatible with the swampland criteria. The spectral index and the running spectral index are within experimental bounds for 0 <p ≤2 . The tensor to scalar ratio is within observational bounds if p ≲O (1 ) .
