The Semicycles of Solutions of Delay Difference Equations
Computers and Mathematics With Applications, 1999 The authors study the semicycles of oscillatory solutions of the delay difference equation \(y_{n+1}-y_n+ p_ny_{n-k}=0\). Upper bounds of numbers of terms of semicycles are determined.

On a class of second-order nonlinear difference equation [PDF]
Advances in Difference Equations, 2011 In this paper, we consider the rule of trajectory structure for a kind of second-order rational difference equation. With the change of the initial values, we find the successive lengths of positive and negative semicycles for oscillatory solutions of ...

On Semicycles of Solutions of Nonlinear Difference Equations With Several Delays
Demonstratio Mathematica, 2003 The authors give an estimate of the upper bound of the number of terms of semicycles of oscillatory solutions of delay difference equations of the form: \((ax_{n+1}+bx_n)^k -(cx_n)^k + \sum_{i=1}^mp_i(n)x_{n-\sigma_i}^k=0\), where \(a,b,c\) are positive reals, \(c>b\), \(k=q/r\), \(q,r\) are odd integers, \(m,\sigma_i\) are positive integers, \(\{ p_i ...

Una perspectiva institucional sobre la relación micro-macro [PDF]
REDES: Revista Hispana para el Análisis de Redes Sociales, 2002 Resumen La relación micro-macro puede ser comprendida como un proceso dinámico en el que los actores interpretan los modelos locales de relación en tanto que indicadores o elementos de una estructura de conjunto, comunican sus interpretaciones y ...

An institutional perspective on the micro-macro link.
REDES: Revista Hispana para el Análisis de Redes Sociales, 2002 The micro-macro link may be regarded as a dynamic process in which actors interpret local patterns of relations as indicators or elements of an overarching structure, communicate their interpretations, and adjust their relations to the overall structure ...
