New fixed points of mixed monotone operators with applications to nonlinear integral equations. [PDF]

open access: yesPLoS ONE
In this paper, first we recall and present some basic results about cone and partial order within the framework of Banach spaces. Next, by means of the properties of cone and monotone iterative techniques, some new fixed point theorems of mixed monotone ...

Monotone method for Riemann-Liouville multi-order fractional differential systems [PDF]

open access: yesOpuscula Mathematica, 2016
In this paper we develop the monotone method for nonlinear multi-order \(N\)-systems of Riemann-Liouville fractional differential equations. That is, a hybrid system of nonlinear equations of orders \(q_i\) where \(0 \lt q_i \lt 1\).

Positive Decreasing Solutions of Higher-Order Nonlinear Difference Equations

open access: yesAdvances in Difference Equations, 2010
It is shown that the decay rates of the positive, monotone decreasing solutions approaching the zero equilibrium of higher-order nonlinear difference equations are related to the positive characteristic values of the corresponding linearized equation. If
