Waves in the Anti-de Sitter space-time Ads
In this talk we address some issues concerning the wave propagation in the 4D+1 anti‐de Sitter space‐time : the role of the conformal boundary, the representation of the fields in term of Kaluza‐Klein tower, the existence of new dynamics associated with a family of novel boundary conditions, the linear stability of a De Sitter brane.
