Numerical integration of the Cartesian equations of motion of a system with constraints: molecular dynamics of n-alkanes
- J. Comput. Phys
, 1977
"... A numerical algorithm integrating the 3N Cartesian equations of motion of a system of N points subject to holonomic constraints is formulated. The relations of constraint remain perfectly fulfilled at each step of the trajectory despite the approximate character of numerical integration. The method ..."

Numerical Integration
- In Encyclopedia of Biostatistics
, 1997
"... This article describes classical quadrature methods and, more briefly, some of the more advanced methods for which software is widely available. The description of the elementary methods in this article borrows from introductory notes by Stewart [31]. An excellent general reference on numerical inte ..."

Numerical Integration of Stochastic Differential Equations
, 1995
"... Abstract. We propose a new concept which allows us to apply any numerical method of weak approximation to a very broad class of stochastic differential equations (SDEs) with nonglobally Lipschitz coefficients. Following this concept, we discard the approximate trajectories which leave a sufficiently ..."

"... In this paper we propose special strategies to compute 1D integrals of functions having weakly or strong singularities at the endpoints of the interval of integration or complex poles close to the domain of integration. As application of the proposed strategies, we compute a four dimensional integra ..."

integral arising from 3D Galerkin boundary element methods (BEM) applied to hypersingular boundary integral equations. In the computation of integrals and in the numerical solution of integral equations, one often has to deal with the numerical integration of functions with endpoint weak singularities
Numerical Integration
"... Introduction After transformation to a canonical element\Omega 0 , typical integrals in the element stiffness or mass matrices (cf. (5.5.8)) have the forms Q = ZZ \Omega 0 ff(; j)N s N T t det(J e )ddj; (6.1.1a) where ff(; j) depends on the coefficients of the partial differential equation an ..."

Backward Error Analysis for Numerical Integrators
- SIAM J. Numer. Anal
, 1996
"... We consider backward error analysis of numerical approximations to ordinary differential equations, i.e., the numerical solution is formally interpreted as the exact solution of a modified differential equation. A simple recursive definition of the modified equation is stated. This recursion is used ..."
