報告摘要:The study of convergence of Fourier series goes back to the very beginning of Fourier analysis around one hundreds years ago, and it, in particular the Bochner-Riesz mean conjecture, has been still stimulating the development of harmonic analysis and beyond. But the noncommutative (or quantum) harmonic analysis was born just recently. In this talk, I shall present the first pointwise convergence of the Fourier series affiliated to von Neumann algebras generated by non-Abelian groups. Without no doubt, this induces many problems. Based on joint works with Simeng Wang and Xumin Wang.
