Regularity properties of the solution to a stochastic heat equation driven by a fractional Gaussian noise on $S^{2}$

Xiaohong Lan, Yimin Xiao

We study the stochastic heat equation driven by an additive infinite dimensional fractional Brownian noise on the unit sphere $S^{2}$ . The existence and uniqueness of its…

Hölder Conditions of Local Times and Exact Moduli of non-differentiability for Spherical Gaussian fields

Xiaohong Lan, Yimin Xiao

This paper investigate the local times and modulus of nondifferentiability of the spherical Gaussian random fields. We extend the methods for studying the local times of Gaussian t…

Strong Local Nondeterminism and Exact Modulus of Continuity for Spherical Gaussian Fields

Xiaohong Lan, Domenico Marinucci, Yimin Xiao

In this paper, we are concerned with sample path properties of isotropic spherical Gaussian fields on $§^{2}$ . In particular, we establish the property of strong local nondeterminism…
