Abstract

On generalized Heisenberg-type groups G(2n,m,U,W)\mathbb{G}(2n,m,\mathbb{U},\mathbb{W}), we give uniform volume estimates for the ball defined by a large class of Carnot-Carath\'{e}odory distances, and establish weak (1, 1) O(Cmn)O(C^m \, n)-estimates for associated centered Hardy-Littlewood maximal functions, extending the results in \cite{BLZ25}. As a by-product, we establish uniformly volume doubling property on Heisenberg groups for a class of left-invariant Riemannian metrics.
