Description
In the context of the AdS(4)/BCFT(3) correspondence, where also the gravitational spacetime is bounded by a hypersurface which encodes the boundary conditions characterising the dual BCFT(3), we study the holographic entanglement entropy of spatial regions with corners, whose vertices are located on the boundary of the BCFT(3). The case where the boundary of the BCFT(3) is a flat hyperplane is considered. Analytic expressions for the simplest corner functions are presented. A relation with the one point function of the stress tensor is discussed. A numerical analysis is performed by computing the area of the minimal area surfaces corresponding to finite domains.
