In this paper we investigate the asymptotic mean-square stability (m.s.-stability) of the family of numerical methods for solving SDE's in the Ito-sense generalizing Rosenbrock's type methods. The connection between the asymptotic m.s.-stability of the numerical method for solving SDE and the…
The paper considers the questions of the numerical analysis of stochastic auto-oscillating systems. The low computer costs variable stepsize algorithms was constructed for solving the non-linear stochastic differential equations. There are given results of numerical experiments obtained with the…
To solve the tree-dimensional static problems in elasticity theory in the displacements a new class of effective iteration methods – factorized operator-triangular methods was studied. The additive expansion of the diagonal operator leads to the analogous expansion of the initial matrix operator in…
By means of the fictitous regions method locally two-sided estimations the initial boundary value problem with the second order parabolic equation of the first type are obtained.
The paper deals with studying the domain decomposition algorithm on two subdomains, where for one of them, which contains sufficiently small number of nodes, is used explicit scheme with small time step, and for another subdomain may be used effective direct algorithm (for example, subdomain is…
A class of nonlinear 1-D parabolic equations with known solutions are introduced. The computer programs for estimation of the absolute errors of numerical methods are decribed.
Strong convergence of interpolating splines on the imbedded meshes is established without the assumption that the system of operators corresponding to the added interpolation conditions is correct. It is also shown that correctness of the system of operators is equivalent to the zero intersection of…
