Iterative methods for solving quadratic Volterra integral equations of the first kind

Известия высших учебных заведений. Поволжский регион: Физико-математические науки
Background. The paper is devoted to the numerical study of integral equations of the first kind with quadratic nonlinearity, which are part of the generalized Volterra integropower series and describe dynamical systems with one input and one output. Such

A new approach to improve ill-conditioned parabolic optimal control problem via time domain decomposition

, 2015
In this paper we present a new steepest-descent type algorithm for convex optimization problems. Our algorithm pieces the unknown into sub-blocs of unknowns and considers a partial optimization over each sub-bloc.

On the numerical calculation of the roots of special functions satisfying second order ordinary differential equations

, 2015
We describe a method for calculating the roots of special functions satisfying second order linear ordinary differential equations. It exploits the recent observation that the solutions of a large class of such equations can be represented via ...

High-precision newton-kantorovich method for nonlinear integral equations

The paper considers the numerical solution of nonlinear integral equations using the Newton-Kantorovich method with the mpmath library. High-precision quadrature of the kernel K(t, s, u) with respect to the variable s for fixed t increases stability and accuracy in problems sensitive to rounding and dispersion.

On the acceleration of the convergence of certain iterative proceedings (II)

Journal of Numerical Analysis and Approximation Theory, 2010
The research reflected in this paper has its origin in the study of the convergence of the sequences generated through the use of certain methods derived from the well-known Newton-Kantorovich method for the approximation of the solution of an equation ...
