The nonconforming virtual element method with curved edges
Lourenco Beirão Da Veiga, Yi Liu, Lorenzo Mascotto +1
We introduce a nonconforming virtual element method for the Poisson equation on domains with curved boundary and internal interfaces. We prove arbitrary order optimal convergence i…
A Weak Galerkin Mixed Finite Element Method for second order elliptic equations on 2D Curved Domains
Yi Liu, Wenbin Chen, Yanqiu Wang
This article concerns the weak Galerkin mixed finite element method (WG-MFEM) for second order elliptic equations on 2D domains with curved boundary. The Neumann boundary condition…
Deleting Items and Disturbing Mesh Theorems for Riemann Definite Integral and Their Applications
Jingwei Liu, Yi Liu
Based on the definition of Riemann definite integral,deleting items and disturbing mesh theorems on Riemann sums are given. After deleting some items or disturbing the mesh of part…
Formula of Volume of Revolution with Integration by Parts and Extension
Yi Liu, Jingwei Liu
A calculation formula of volume of revolution with integration by parts of definite integral is derived based on monotone function, and extended to a general case that curved trape…
Parameter Estimation of Jelinski-Moranda Model Based on Weighted Nonlinear Least Squares and Heteroscedasticity
Jingwei Liu, Yi Liu, Meizhi Xu
Parameter estimation method of Jelinski-Moranda (JM) model based on weighted nonlinear least squares (WNLS) is proposed. The formulae of resolving the parameter WNLS estimation (WN…
