An alternative and easy approach to fixed point results via simulation functions

2017

Abstract We discuss, extend, improve and enrich results on simulation functions established by several authors. Furthermore, by using Lemma 2.1 of Radenovic et al. [Bull. Iran. Math. Soc., 2012, 38, 625],we get much shorter and nicer proofs than the corresponding ones in the existing literature.

Mercenari italici in viaggio verso l’entroterra della Sicilia? Il contributo delle evidenze numismatiche e archeologiche

2014

The subject of the contribution is the analysis of a series of numismatic evidences, coming from Amorella, Monte Raffe, Castellazzo di Marianopoli, Santa Caterina di Villarmosa, through which it is possible to observe how, from the mid-4th century BC, the hinterland had become a veritable enclave of mercenaries. These are allogeneic groups, who presumably arrived in Sicily from the Italian peninsula to serve as soldiers in the ranks of the Dionysian armies, and were subsequently exhorted or chose to settle permanently in the indigenous communities of the interior

Nonlinear contractions involving simulation functions in a metric space with a partial order

2015

Very recently, Khojasteh, Shukla and Radenovic [F. Khojasteh, S. Shukla, S. Radenovic, Filomat, 29 (2015), 1189-1194] introduced the notion of Z-contraction, that is, a nonlinear contraction involving a new class of mappings namely simulation functions. This kind of contractions generalizes the Banach contraction and unifies several known types of nonlinear contractions. In this paper, we consider a pair of nonlinear operators satisfying a nonlinear contraction involving a simulation function in a metric space endowed with a partial order. For this pair of operators, we establish coincidence and common fixed point results. As applications, several related results in fixed point theory in a …

Sekaiza | Sekeiza | Sekaisa

2022

La ceca de Sekaiza se localizó en el yacimiento de Poyo de Mara, hasta ca. 153 a.C., y posteriormente se desplazó al yacimiento de Belmonte, permaneciendo en ese lugar hasta mediados del siglo I a.C., quizás fue destruida durante las Guerras Sertorianas (Burillo y Ostalé 1984: 305-309; Gomis 2001: 33; Burillo 2006: 203-240; Asensio 2001: 89). Se ha discutido la posibilidad de que esta ceca y Bilbilis, dada su proximidad, emitieran moneda de manera simultánea (Burillo, Ostalé 1984), aunque Villaronga (1988) propone una jerarquización de sus emisiones que las haría compatibles. Es una de las cecas celtibéricas con mayor volumen de producción y cantidad de hallazgos. La producción monetaria ha…

Well GeHP detector calibration for environmental measurements using reference materials

2016

International audience; A well-type detector installed in the Modane underground Laboratory (LSM) can combine both low background and high detection efficiency and it is well suited for the analysis of small amounts of environmental samples. Reference materials such as IAEA-447 (moss-soil), IAEA-RG-Th1 and IAEA-RG-U1 were used for the detector calibration, owing to a chemical composition close to those of the environmental samples. Nevertheless , the matrix effects and the true coincidence summing effects must be corrected from the full energy peak efficiency (FEPE). The FEPE was performed for a wide range of energy by a semi-empirical method using Monte Carlo simulation (MCNP6), intended f…

Kinematical coincidence method in transfer reactions

2013

A new method to extract high resolution angular distributions from kinematical coincidence measurements in binary reactions is presented. Kinematic is used to extract the center of mass angular distribution from the measured energy spectrum of light particles. Results obtained in the case of 10Be+p-->9Be+d reaction measured with the CHIMERA detector are shown. An angular resolution of few degrees in the center of mass is obtained.

Some common fixed point results for weakly compatible mappings in cone metric type space

2013

In this paper we consider cone metric type spaces which are introduced as a generalization of symmetric and metric spaces by Khamsi and Hussain in 2010. Then we prove several common fixed point for weakly compatible mappings in cone metric type spaces. All results are proved in the settings of a solid cone, without the assumption of continuity of the mappings.

The role of Institutions in explaining wage determination in the Euro Area: a panel cointegration approach

2016

Over the last 15 years, the evolution of labor costs has been very diverse across EMU countries. Since wages have important second-round effects on prices and competitiveness, and EMU countries do not have the tool of the nominal exchange rate to correct for such imbalances, understanding the determinants of the wage is a matter of increasing concern and debate. We estimate the equilibrium wage equation for the Euro Area over the period 1995-2011 using panel cointegration techniques that allow for cross-section dependence and structural breaks. The results show that the equilibrium wage has a positive relation with productivity and negative relation with unemployment, as expected. We also i…

The euro impact on trade: long run evidence with structural breaks

2012

In this paper we present new evidence on the euro effect on trade. We use a data set containing all bilateral combinations in a panel of 26 OECD countries during the period 1967-2008. From a methodological point of view, we implement a new generation of tests that allow solving some of the problems derived from the non-stationary nature of the data. To this aim we apply panel tests that account for the presence of cross-section dependence as well as discontinuities in the non-stationary panel data. We test for cointegration between the variables using panel cointegration tests, especially the ones proposed by Banerjee and Carrióni- Silvestre (2010). We also efficiently estimate the long-run…
