Bimetric, conformal supergravity and its superstring embedding
Abstract We discuss the connection between Weyl2 supergravity and superstrings and further discuss holography between 4-dimensional, N $$ mathcal{N} $$ = 4 superconformal Weyl2 supergravity and N $$ mathcal{N} $$ = 8, higher spin-four theory on AdS 5.The Weyl2 plus Einstein supergravity theory is a special kind of a bimetric gravity theory and cons
