摘要
关于最大类型的差分方程,Ladas、Stevic等人提出了一系列公开问题,Mishev D P、Kenneths等人已解决了其中许多问题.作者研究了一个差分方程正解的有界性,证明了这个方程的每一个正解是有界的,部分回答了Ladas G、Stevic S等人在文献[1-2]中提出的公开问题,部分推广了Kenneths在文献[4]中得出的结论.
Ladas and Stevic proposed some open problems about max-type difference equation,some of which have already been solved by Mishev,Kenneths et al.In this paper,we studied the boundedness of positive solutions of the max-type difference equation.We showed that every positive solution of this equation was bounded,partially gave answer to some of the problems by Ladas G and Stevic S in articles of and partially extended the findings of Kenneths in article [4] to general conditions.
