Resumo

This talk will survey some folklore theorems about the interaction between the theory of Lie groupoids and geometric stacks on the site of smooth manifolds. To do this, a more general theorem about the relationship between geometric stacks on a site and internal groupoids will be discussed. I will show how considering alternative sites can be applied to studying Morita equivalences of Lie groupoids equipped with additional geometry.
