## The Kato Square Root Problem for Divergence Form Operators with Potential »

Julian Bailey (MSI)
1.30pm 3 April 2018

The Kato square root problem for divergence form elliptic operators is the equivalence statement $\norm{\sqrt{- \mathrm{div} \br{A \nabla}}u} \simeq \norm{\nabla u}$, where  $A$ is a complex matrix-valued function.
