摘要
本文主要考察以下具有强迫振动项的高阶泛函差分方程△mx_n+nΣ_(i=1)q_i(n)f(x_(n-τi))=c_n.我们研究三种情况:q_i(n)≥0,q_i(n)〈0或q_i(n)是变号的.其中,强迫振动项cn没有设定限制.
Some new criteria for the Higher- order Nonlinear functional Di. erence Equa- tions of the from △mx_n+nΣ_(i=1)q_i(n)f(x_(n-τi))=c_n have been established under three conditions: q_i(n)≥0,q_i(n)0,orq_i(n) alternated with Positive and Negative. The forcing term cnhas no limit set.
