In this article, we investigate the existence of positive solutions for second-order m-point boundary-value problems at resonance on the half-line (q(t)x′(t))′ = f(t, x(t), x′(t)), a.e. in (0,∞), x(0) = m−2 X i=1 αix(ξi), lim t→∞ q(t)x′(t) = 0. Some existence results are obtained by using the Mawhin’s coincidence theory.

We introduce the concept of mixed (G,S)-monotone mappings and prove coupled coincidence point theorems for such mappings satisfying a nonlinear contraction involving altering distance functions. Presented theorems extend, improve and generalize the recent results of Harjani, López and Sadarangani [J. Harjani, B. López and K. Sadarangani, Fixed point theorems for mixed monotone operators and app...

‎The purpose of this paper is to establish some coupled coincidence point theorems for mappings having a mixed $g$-monotone property in partially ordered metric spaces‎. ‎Also‎, ‎we present a result on the existence and uniqueness of coupled common fixed points‎. ‎The results presented in the paper generalize and extend several well-known results in the literature‎.

The purpose of this paper is to establish some coupled coincidence point theorems for a pair of mappings without mixed monotone property satisfying a contractive condition of rational type in the framework of partially ordered metric spaces. Also, we present a result on the existence and uniqueness of coupled common fixed points. The results presented in the paper generalize and extend several ...

Clivus chordoma coincidence with arachnoid cyst is rare. We report a rare case of clivus chordoma associated with arachnoid cyst.

In this paper, we obtain coupled coincidence and coupled fixed points of mappings satisfying a non linear contractive condition in partially ordered partial metric spaces. Our results generalize the theorems of H.Aydi [4] and W. Shatanawi et.al. [20]. We also provide an example to support our results. AMS (MOS) Subject Classification Codes: 54H25, 47H10

Overlap coincidence is an equivalent criterion to pure discrete spectrum of the dynamics of self-affine tilings in R. In the case of d = 1, strong coincidence on m-letter irreducible substitution has been introduced in [10, 8] which implies that the system is metrically conjugate to a domain exchange in Rm−1. However being a domain exchange does not imply the property of pure discrete spectrum ...
