On necessary and sufficient conditions for -estimates of Riesz transforms associated to elliptic operators on $\RR^n$ and related estimates
Pascal Auscher
This article focuses on estimates for objects associated to elliptic operators in divergence form: its semigroup, the gradient of the semigroup, functional calculus, square f…
Hardy spaces and divergence operators on strongly Lipschitz domains in
P. Auscher, E. Russ
Let be a strongly Lipschitz domain of $\reel^n$. Consider an elliptic second order divergence operator (including a boundary condition on ) and define a Hardy sp…
Lectures on the Kato square root problem
P. Auscher
This is the text of a series of three lectures given at the CMA of the Australian National University on the recent solution of the square root problem for divergence form elliptic…
Carleson measures, trees, extrapolation, and theorems
Pascal Auscher, Steve Hofmann, Camil Muscalu +2
The theory of Carleson measures, stopping time arguments, and atomic decompositions has been well-established in harmonic analysis. More recent is the theory of phase space analysi…
