The Kato square root estimate with Robin boundary conditions

Sebastian Bechtel, Andreas RosÃ©n

We prove the Kato square root estimate for second-order divergence form elliptic operators $- d i v (A \nabla)$ on a bounded, locally uniform domain $D \subseteq R^{n}$ , for accr…

A second order approach to the Kato square root problem on open sets

Sebastian Bechtel, Cody Hutcheson, Tim Schmatzler +2

We obtain the Kato square root property for coupled second-order elliptic systems in divergence form subject to mixed boundary conditions on an open and possibly unbounded set in $…

Weighted non-autonomous $L^{q} (L^{p})$ maximal regularity for complex systems

Sebastian Bechtel

We show weighted non-autonomous $L^{q} (L^{p})$ maximal regularity for families of complex second-order systems in divergence form under a mixed regularity condition in space and time.…
