Sharp Estimates for Jacobi Heat Kernels in Double Conic Domains
Dawid Hanrahan
We study the even and odd Jacobi heat kernels defined in the context of the multidimensional double cone and its surface, the multidimensional hyperboloid and its surface, and the…

Sharp estimates for Jacobi heat kernels in conic domains
Dawid Hanrahan, Dariusz Kosz
We prove genuinely sharp estimates for the Jacobi heat kernels introduced in the context of the multidimensional cone and its surface . To do…
