On the stability of meshless symmetric collocation for boundary value problems
, 2007 In this paper, we study the stability of symmetric collocation methods for boundary value problems using certain positive definite kernels. We derive lower bounds on the smallest eigenvalue of the associated collocation matrix in terms of the separation ...

Stabilizer-free weak Galerkin finite element for linear elastic problems
四川大学学报. 自然科学版Linear elastic problem originates from engineering applications such as machinery and aviation.Due to the complexity of differential equation in the linear elastic problem， the analytic solutions of the problem are still unknown.Although the classical ...

Stability Analysis of Wilson's Element for Incompressible Elasticity
, 1994 In this work, the rectangular nonconforming Wilson element in solving incompressible elastic equation is analyzed. Although the element does not satisfies the inf-sup condition (in a mixed formulation), it still can be used to compute the displacement ...

Crouzeix-Raviart type finite elements on anisotropic meshes
, 1999 The paper deals with a non-conforming finite element method on a class of anisotropic meshes. The Crouzeix-Raviart element is used on triangles and tetrahedra. For rectangles and prismatic (pentahedral) elements a novel set of trial functions is proposed.

, 1995 We introduce and analyze stable discrete spaces with quasioptimal approximation properties (with respect to increasing polynomial degree). This will pertain to some general classes of problems: scalar and systems of elliptic as well as semi-elliptic ...

A DUAL LEAST-SQUARES FINITE ELEMENT METHOD FOR LINEAR HYPERBOLIC PDES: A NUMERICAL STUDY
, 2008 . In this paper, we develop a least-squares finite element method for linear Partial Differential Equations (PDEs) of hyperbolic type. This formulation allows for discontinuities in the numerical approximation and yields a linear system which can be ...

Computable convergence bounds for GMRES
, 1998 The main purpose of this paper is the derivation of computable bounds on the residual norms of (full) GMRES. The new bounds depend on the initial guess and thus are conceptually different from standard 'worst-case' bounds. The analysis is valid
