Subdominant positive solutions of the discrete equation Δu(k+n)=−p(k)u(k) [PDF]
Abstract and Applied Analysis, 2004 A delayed discrete equation Δu(k+n)=−p(k)u(k) with positive coefficient p is considered. Sufficient conditions with respect to p are formulated in order to guarantee the existence of positive solutions if k→∞.
