In this paper, we study codimension two holography in flat spacetimes, based on the idea of wedge holography. We propose that a region $d+1$ dimensional spacetime surrounded by end world branes, which are given $d$ hyperbolic spaces, is dual to conformal field theory (CFT) $d\ensuremath{-}1$ sphere. Similarly, also bounded de Sitter spaces holographically CFT Our calculations partition function...
