Analytical and numerical investigation on the tempered time-fractional operator with application to the Bloch equation and the two-layered problem
Libo Feng, Fawang Liu, Vo V. Anh +1
In the continuous time random walk model, the time-fractional operator usually expresses an infinite waiting time probability density. Different from that usual setting, this work…
Fractional Stochastic Partial Differential Equation for Random Tangent Fields on the Sphere
Vo V. Anh, Andriy Olenko, Yu Guang Wang
This paper develops a fractional stochastic partial differential equation (SPDE) to model the evolution of a random tangent vector field on the unit sphere. The SPDE is governed by…
On LSE in regression model for long-range dependent random fields on spheres
Vo Anh, Andriy Olenko, Volodymyr Vaskovych
We study the asymptotic behaviour of least squares estimators in regression models for long-range dependent random fields observed on spheres. The least squares estimator can be gi…
On Approximation for Fractional Stochastic Partial Differential Equations on the Sphere
Vo V. Anh, Philip Broadbridge, Andriy Olenko +1
This paper gives the exact solution in terms of the Karhunen-Loève expansion to a fractional stochastic partial differential equation on the unit sphere $\mathbb{S}^{2}\subset \mat…
On rate of convergence in non-central limit theorems
Vo Anh, Nikolai Leonenko, Andriy Olenko +1
The main result of this paper is the rate of convergence to Hermite-type distributions in non-central limit theorems. To the best of our knowledge, this is the first result in the…
Multifractality and Laplace spectrum of horizontal visibility graphs constructed from fractional Brownian motions
Zu-Guo Yu, Huan Zhang, Da-Wen Huang +2
Many studies have shown that additional information can be gained on time series by investigating their associated complex networks. In this work, we investigate the multifractal p…
