WebSep 5, 2024 · This kernel is defined as the fundamental solution to the heat equation \begin {aligned} \Delta _ {M} u (t;x) = \frac {\partial } { \partial t} u (t;x) \end {aligned} on (0,\infty )\times M with a initial datum. It plays a crucial role in different branches of mathematics and mathematical physics.
