Monotone iterative technique for causal differential equations with upper and lower solutions in the reversed order

*Correspondence: [email protected] Department of Information Engineering, China University of Geosciences Great Wall College, Baoding, Hebei 071000, P.R. China Abstract In this paper, we use monotone iterative technique in the presence of (coupled) upper and lower solutions in the reversed order to discuss the existence of extremal solutions (quasi-solutions) for causal differential equations wit...

Monotone Iterative Method and Regular Singular Nonlinear Bvp in the Presence of Reverse Ordered Upper and Lower Solutions

Monotone iterative technique is employed for studying the existence of solutions to the second-order nonlinear singular boundary value problem − ` p(x)y′(x) ́′ + p(x)f ` x, y(x), p(x)y′(x) ́ = 0 for 0 < x < 1 and y′(0) = y′(1) = 0. Here p(0) = 0 and xp′(x)/p(x) is analytic at x = 0. The source function f(x, y, py′) is Lipschitz in py′ and one sided Lipschitz in y. The initial approximations are...

Lower-dose CT urography (CTU) with iterative reconstruction technique in children – initial experience and examination protocol

BACKGROUND Conventional X-ray urography is one of the basic imaging techniques in urinary tract diseases in children. CT urography (CTU) employing standard Filtered Back Projection (FBP) reconstruction algorithms is connected with higher radiation dose. Advanced iterative reconstruction techniques enable lowering the radiation dose to the level comparable with conventional X-ray urography with ...

On Lower and Upper Solutions without Ordering on Time Scales

In order to enlarge the set of boundary value problems on time scales, for which we can use the lower and upper solutions technique to get existence of solutions, we extend this method to the case when the pair lacks ordering. We use the degree theory and a priori estimates to obtain the existence of solutions for the second-order Dirichlet boundary value problems. To illustrate a wider applica...
