| 1 | EXISTENCE OF POSITIVE SOLUTIONS AND 1/c-GLOBAL ATTRACTIVITY OF A NONLINEAR DELAY DIFFERENCE EQUATION WITH VARIABLE COEFFICIENTS显示文摘The existence of positive solutions and the global attractivity of the difference equation Δy n=r ny nK-y n-l n K-cy n-l n are investigated. And some sufficient conditions are obtained,which greatly improve and extend the known results. | MaManjun TangHengsheng WangZhicheng | 2001 | Applied Mathematics(A Journal of Chinese Universities)2001，16，3： | 1 |
