Localisation of Spectral Sums corresponding to the sub-Laplacian on the Heisenberg Group

Rahul Garg, K. Jotsaroop

In this article we study localisation of spectral sums $\{S_R{\}}_{R>0}$ associated to the sub-Laplacian $\mathcal{L}$ on the Heisenberg Group ${\mathbb{H}}^d$ where $S_R f := \int_0…
