Abstract

We derive a new three-dimensional Hardy-type inequality for a cube for the class of functions from the Sobolev space H1 having zero trace on small holes distributed periodically along the boundary. The proof is based on a careful analysis of the asymptotic expansion of the first eigenvalue of a related spectral problem and the best constant of the corresponding Friedrichs-type inequality.
