Various sharp estimates for semi-discrete Riesz transforms of the second order
Komla Domelevo, Adam Osekowski, Stefanie Petermichl
We give several sharp estimates for a class of combinations of second order Riesz transforms on Lie groups that are multiply connected, composed of a d…

Stability in Burkholder's differentially subordinate martingales inequalities and applications to Fourier multipliers
Rodrigo Banuelos, Adam Osekowski
We study stability estimates for the almost extremal functions associated with the -bound for the real and imaginary parts of the Beurling-Ahlfors operator. The proof exploits…
