| contents | The swampland conjectures from String theory have had very interesting implications for cosmology and particularly for Inflation. It has been shown that the single field inflationary models in a GR based cosmology are in unavoidable tensions with these conjectures and so it becomes interesting to see whether there is a way to overcome the issues of the swampland and single field inflation in an essentially GR based cosmology. We show that this can be the case if one considers a certain type of Lorentz violating inflationary scenario. We work out the requirements for these inflationary models to be swampland consistent and then show how this scenario allows some popular inflationary potentials to be swampland consistent as well. |
