We present an $LC$ circuit model that supports a tilted ``Dirac cone'' in its spectrum. The tilt of the Dirac cone is specified by parameters consisting mutual inductance between neighboring sites and capacitance ${C}_{0}$ at every lattice site. These can be completely measured impedance spectroscopy. Given described background spacetime metric, spectroscopy perfectly provide (local) informatio...

The object of this paper is to establish a theorem for a unique common fixed point of four self mappings, weakly compatibile in pairs and satisfying a generalized contractive condition in a cone metric space. Our result generalizes and synthesizes the results of Abbas– Jungck [1], Arshad et al. [2], Huang–Zhang [3] and Vetro [8].

In this paper, we introduce a new concept on a complete generalized D∗-metric space by using the concept of generalized D∗-metric space (D∗-cone metric space) called ∇∗∗-distance and, by using the concept of the ∇∗∗-distance we prove some new fixed point theorems in complete partially ordered generalized D∗-metric space which is the main result of our paper. c ©2015 All rights reserved.

Fixed point and common fixed point results for generlized contractive mappings are obtianed in ordered cone metric spaces.

In this note, we prove common fixed point for a Banach pair of mappings on D∗-Generalized Cone Metric Space.
