Cutoff profiles for quantum Lévy processes and quantum random transpositions
Amaury Freslon, Lucas Teyssier, Simeng Wang
We consider a natural analogue of Brownian motion on free orthogonal quantum groups and prove that it exhibits a cutoff at time . Then, we study the induced classical proc…

Singularity of the generator subalgebra in mixed -Gaussian algebras
Simeng Wang
We prove that for the mixed -Gaussian algebra associated to a real Hilbert space and a real symmetric matrix with $\sup|q_{…

Quantum symmetries on noncommutative complex spheres with partial commutation relations
Simeng Wang
We introduce the notion of noncommutative complex spheres with partial commutation relations for the coordinates. We compute the corresponding quantum symmetry groups of these sphe…
