Uniform heat kernel asymptotics for the Grushin operator
Yimeng Chen, Hong-Quan Li, Jun-Cheng Tang +1
Adopting the powerful methods introduced in \cite{li2021carnotcaratheodory, LZ2025}, we investigate the asymptotic behaviour at infinity for the heat kernel associated with the Gru…

Revisiting the heat kernel on isotropic and nonisotropic Heisenberg groups
Hong-Quan Li, Ye Zhang
The aim of this paper is threefold. First, we obtain the precise bounds for the heat kernel on isotropic Heisenberg groups by using well-known results in the three dimensional case…
