Abstract: 

We discuss recent sharp Bochner-Riesz estimates for sub-Laplacians on Heisenberg groups. Since favorable restriction estimates fail in this setting, we developed an approach that relies on square function bounds for the wave equation associated with the sub-Laplacian. This is joint work with Detlef Müller, Andreas Seeger, and Betsy Stovall.
