The Kato square root problem on an arbitrary domain of $\mathbb{R}^d$ (1902.01101v2)
Published 4 Feb 2019 in math.AP and math.FA
Abstract: We solve the Kato square root problem for general elliptic operators and systems with measurable and complex coefficients on any domain of the Euclidean space. The operators are subject to Dirichlet boundary conditions. We also allow perturbations by general complex potentials.
