Convex set of quantum states with positive partial transpose analysed by hit and run algorithm
Konrad Szymański, Benoît Collins, Tomasz Szarek +1
The convex set of quantum states of a composite system with positive partial transpose is analysed. A version of the hit and run algorithm is used to generate a sequen…
Maximal operators of exotic and non-exotic Laguerre and other semigroups associated with classical orthogonal expansions
Adam Nowak, Peter Sjögren, Tomasz Z. Szarek
Classical settings of discrete and continuous orthogonal expansions, like Laguerre, Bessel and Jacobi, are associated with second order differential operators playing the role of t…
On Harmonic Analysis Operators in Laguerre-Dunkl and Laguerre-Symmetrized Settings
Adam Nowak, Krzysztof Stempak, Tomasz Z. Szarek
We study several fundamental harmonic analysis operators in the multi-dimensional context of the Dunkl harmonic oscillator and the underlying group of reflections isomorphic to $\m…
