S. L. Woronowicz


Stanisław Lech Woronowicz is a Polish mathematician and physicist. He is affiliated with the University of Warsaw and is a member of the Polish Academy of Sciences.
It was Woronowicz, and Erling Størmer, who classified positive maps in the low-dimensional cases. This translates to the Peres-Horodecki criterion, in the context of quantum information theory. He is also known for contributions to quantum groups.
