On the oscillation of a class of linear homogeneous third order differential equations

N. Parhi, P. Das (1998)

Archivum Mathematicum

In this paper we have considered completely the equation $y^{'''} + a (t) y^{''} + b (t) y^{'} + c (t) y = 0, (*)$ where $a \in C^{2} ([σ, \infty), R)$ , $b \in C^{1} ([σ, \infty), R)$ , $c \in C ([σ, \infty), R)$ and $σ \in R$ such that $a (t) \leq 0$ , $b (t) \leq 0$ and $c (t) \leq 0$ . It has been shown that the set of all oscillatory solutions of (*) forms a two-dimensional subspace of the solution space of (*) provided that (*) has an oscillatory solution. This answers a question raised by S. Ahmad and A. C. Lazer earlier.

On the oscillatory integration of some ordinary differential equations

Octavian G. Mustafa (2008)

Archivum Mathematicum

Conditions are given for a class of nonlinear ordinary differential equations $x^{''} + a (t) w (x) = 0$ , $t \geq t_{0} \geq 1$ , which includes the linear equation to possess solutions $x (t)$ with prescribed oblique asymptote that have an oscillatory pseudo-wronskian $x^{'} (t) - \frac{x (t)}{t}$ .

On the rate of convergence to the neutral attractor of a family of one-dimensional maps

T. Nowicki, M. Sviridenko, G. Świrszcz, S. Winograd (2009)

Fundamenta Mathematicae

For a family of maps $f_{d} (p) = 1 - {(1 - p / d)}^{d}$ , d ∈ [2,∞], p ∈ [0,1]. we analyze the speed of convergence (including constants) to the globally attracting neutral fixed point p = 0. The study is motivated by a problem in the optimization of routing. The aim of this paper is twofold: (1) to extend the usage of dynamical systems to unexplored areas of algorithms and (2) to provide a toolbox for a precise analysis of the iterates near a non-degenerate neutral fixed point.
