Abstract:

We discuss the value of the best constant in Gaffney inequality namely $$ \lVert \nabla \omega \rVert{L{2}}{2}\leq C\left( \lVert d\omega\rVert{L{2}}{2}+\lVert \delta\omega\rVert{L{2}% }{2}+\lVert \omega\rVert{L{2}}{2}\right) $$ when either $\nu\wedge\omega=0$ or $\nu\,\lrcorner\,\omega=0$ on $\partial\Omega.$
