Hardy inequalities for inverse square potentials with countable number of singularities

Cristian Cazacu, Aurora Marica

The Hardy Inequality (HI) for potentials with countably many singularities of the form $V={\sum }_{k\in \mathbf{Z}}\frac{1}{|x-a_k{|}^2}$ is not a trivial issue. In principle, the more…
