Revisiting the conformal invariance of the scalar field: from Minkowski space to de Sitter space

E. Huguet, J. Queva, J. Renaud

In this article, we clarify the link between the conformal (i.e. Weyl) correspondence from the Minkowski space to the de Sitter space and the conformal (i.e. SO(2,$d$)) invariance…
