On some one-step implicit methods as dynamical systems [PDF]
The one-step implicit methods, the backward Euler being the most known, require the solution of a nonlinear equation at each step.To avoid this, these methods can be approximated by making use of a one step of a Newton method.

\^A-and \^I-stability of collocation Runge-Kutta methods
This paper deals with stability of classical Runge-Kutta collocation methods. When such methods are embedded in linearly implicit methods as developed in [12] and used in [13] for the time integration of nonlinear evolution PDEs, the stability of these ...

On the convergence of a method for solving two point boundary value problems by optimal control [PDF]
Using the idea of the least squares method, a nonlinear two point boundary value problem is transformed into an optimal control problem. For solving the optimal control problem the gradient method is used.

Functions with bounded E-d-variation on undirected tree networks [PDF]
In this paper we define and study functions with bounded \(E-d\)-variation on undirected tree networks. For these functions with bounded \(E-d\)-variation we establish a Jordan type theorem.

Minisum location problems in directed networks [PDF]
We study some location problems in directed networks: we define circular medians and p-circular medians, \(p>1\). We present an algorithm for establishing circular medians.
