On the discrete Poincaré inequality for B-schemes of 1D Fokker-Planck equations in full space

Lei Li, Jianguo Liu, Zhen Wang

In this paper, we propose two approaches to derive the discrete Poincaré inequality for the B-schemes, a family of finite volume discretization schemes, for the one-dimensional Fokker-Planck equation in full space. We study the properties of the spatially discretized Fokker-Planck equation in …

Some Grönwall Inequalities for a Class of Discretizations of Time Fractional Equations on Nonuniform Meshes

Yuanyuan Feng, Lei Li, Jianguo Liu, Tao Tang

Abstract. We consider the completely positive discretizations of fractional ordinary differential equations (FODEs) on nonuniform meshes. Making use of the resolvents for nonuniform meshes, we first establish comparison principles for the discretizations. Then we prove some discrete Grönwall inequalities using the comparison …

Adaptive Orthogonal Basis Function Detection Method for Unknown Magnetic Target Motion State

Zitong Wang, Jianguo Liu, Tuo Guo

Traditional methods of orthogonal basis function decomposition have been extensively used to detect magnetic anomaly signals. However, the determination of the relative velocity between the detection platform and the magnetic target remains elusive in practical detection. And, the non-ideal uniform motion of …
