Title Braneworld setup and embedding in teleparallel gravity
Type JournalPaper
Keywords Teleparallel gravity Braneworld gravity
Abstract We construct the setup of a five-dimensional braneworld scenario in teleparallel gravity. Both cases of Minkowski and Friedmann–Robertson–Walker branes embedded in anti-de Sitterbulk are studied and the effective 4Daction were studied. 4-dimensional local Lorentz invariance is found to be recovered in both cases. However, due to different junction conditions, the equations governing the 4Dcosmological evolution differ from general relativistic case. Using the results of Ref.[13], we consider a simple inflationary scenario in this setup. The inflation parameters are found to be modified compared to general relativistic case.
