An estimate on the Hessian of the heat kernel

  • Daniel W. Stroock

Summary

Let M be a compact, connected Riemannian manifold, and let p t (x, y) denote the fundamental solution to Cauchy initial value problem for the heat equation \(\frac{\partial u}{\partial t}=\frac{1}{2}\Delta u\), where Δ is the Levi-Civita Laplacian. The purpose of this note is to show that the Hessian of log p t (·, y) at x is bounded above by a constant times \(\frac{1}{t}+\frac{dist{{\left( x,y \right)}^{2}}}{{{t}^{2}}}\) for t ∈ (0, 1].
