We study the propagation of errors in the numerical integration of perturbations of relative equilibrium solutions of Hamiltonian differential equations with symmetries. First it is shown that taking an initial perturbation of a relative equilibrium, the corresponding solution is related, in a first ...

Numerical IntegrationAlgorithms with Automatic Result VerificationRoundoff ErrorIn this work, we consider different numerical methods for the approximation of definite integrals. The three basic methods used here are the Midpoint, the Trapezoidal, and Simpson's rules. We trace the behavior of the ...
Numerical solution of ODEsRunge-Kutta methodsglobal errorchemical kinetic modelWe describe an effective computational procedure of obtaining estimate for the global error in the long-term numerical integration with one-step embedded explicit Runge-Kutta methods applied to an ODE system. The paper relies...
numerical integration dimension errorYou may not be expecting NAN, but that is how to make Y from X. Look at the exponent, it has values from -590 to -Inf. What do you think e^-590 is? ZERO (for all intents and purposes).
