Hardy-type inequalities in arbitrary domains with finite inner radius

We prove Hardy-type inequalities in spatial domains with finite inner radius, in particular, one-dimensional $L^p$-inequalities and their multidimensional analogs. The powers of the distance to the boundary of a set occur in the weight functions of spatial inequalities. It is demonstrated that the constant is sharp of the $L^1$-inequalities in one-dimensional and multidimensional cases for convex domains.
