Positive solutions for a class of non-autonomous second order difference equations via a new functional fixed point theorem
Year: 2022
Type: article
Abstract: In this paper, by using recent results on fixed point index, we develop a new fixed point theorem of functional type for the sum of two operators $T+S$ where $I-T$ is Lipschitz invertible and $S$ a $k$-set contraction. This fixed point theorem is then used to establish a new result on the existence of positive solutions to a non-autonomous second order difference equation.
