Hessian of the Busemann function on Damek-Ricci spaces

Hiroyasu Satoh

In this note, we calculate the Hessian of the Busemann function on a Damek-Ricci space. We investigate the eigenvalues of the Hessian and show its positive definiteness (Theorem 1)…

Harmonic Hadamard manifolds and Gauss hypergeometric differential equations

Mitsuhiro Itoh, Hiroyasu Satoh

A new class of harmonic Hadamard manifolds, those spaces called of hypergeometric type, is defined in terms of Gauss hypergeometric equations. Spherical Fourier transform defined o…

Hessian of Busemann functions and rank of Hadamard manifolds

Mitsuhiro Itoh, Sinwhi Kim, JeongHyeong Park +1

In this article we show that every geodesic is rank one and the Hessian of Busemann functions is positive definite for a harmonic Damek-Ricci space, a two step solvable Lie group w…
