Efficient Preprocessing Methods for Quantifier Elimination,d a simple check for non-vanishing of denominators in substitutions. Yet we present examples of quantified formulas which can be reduced by our preprocessing method to problems solvable by current quantifier elimination packages, whereas the original formulas had been inaccessible to those.

Numerical Study of Stability Domains of Hamiltonian Equation Solutions,rch [3,4,5,6,7,8,9,10] has grown recently due to the fact that the existence of central configurations of the many-body problem is eventually reduced to the solution of the systems of nonlinear algebraic-irrational equations, which can be solved only by the computer algebra methods, thanks to exceptional properties of them.

Numeric-Symbolic Computations in the Study of Central Configurations in the Planar Newtonian Four-Bions in the form of antiparallelogram. We have shown also that central configuration may be deformed continuously by means of changing masses of the bodies and found two-parametric family of central configurations in the neighborhood of the square.

A Symbolic-Numerical Algorithm for Solving the Eigenvalue Problem for a Hydrogen Atom in Magnetic Fd on the parameter, their derivatives with respect to the parameter and matrix elements is presented. The efficiency and accuracy of the algorithm and of the numerical scheme derived are confirmed by computations of eigenenergies and eigenfunctions for the low-excited states of a hydrogen atom in the uniform magnetic field.

Besides, the development of so-called perturbation function is not required (essential fact). These solutions are valid in principle for infinite time interval unlike known classical solutions of such problem. Such solutions are obtained for the first time.
