The problem of boundary behaviour at the origin of coordinates is discussedfor D-dimensional Schrodinger equation in the framework of hyper sphericalformalism, which have been often considered last time. We show that theDirichlet condition, which seems as natural, is not mathematically welljustified, on the contrary to the 3-dimensional case. The stronger argument infavour of Dirichlet boundary condition is the requirement of time independenceof wave functions norm. The problem remains open for singular potentials.
