  We study the holographic entanglement entropy of spatial regions with corners
in the AdS4/BCFT3 correspondence by considering three dimensional boundary
conformal field theories whose boundary is a timelike plane. We compute
analytically the corner function corresponding to an infinite wedge having one
edge on the boundary. A relation between this corner function and the
holographic one point function of the stress tensor is observed. An analytic
expression for the corner function of an infinite wedge having only its tip on
the boundary is also provided. This formula requires to find the global minimum
among two extrema of the area functional. The corresponding critical
configurations of corners are studied. The results have been checked against a
numerical analysis performed by computing the area of the minimal surfaces
anchored to some finite domains containing corners.
