Abstract:
We are concerned with the sharp Hardy-Leray inequalities for curl-free vector fields $u \in C_0^{\infty}(\mathbb{R}^N)^N$. The result complements the former work by Costin-Maz`ya on the sharp Hardy-Leray inequalities for the axisymmetric divergence-free vector fields. The sharp Rellich-Leray inequalities for curl-free vector fields are also shown. This talk is based on a joint work with N. Hamamoto (Osaka City Univ.).
