The purpose of this paper is to extend the fixed point results of maps satisfying weak contractivity condition introduced by Bhaskar and Lakshmikantam [T. Gnana Bhaskar and V. Lakshmikantham, Fixed point theorem in partially ordered metric spaces and applications, Non-linear Analysis, 65 (2006), 1379-1393] to the case of contractions with rational expressions in partially ordered metric spaces. Examples are provided in support of our results. Our theorems generalize the results of Bhaskar and Lakshmikantam [2].

The aim of this paper is to prove some common fixed point theorems for two pairs of selfmaps in complete metric spaces by assuming weak commutativity assumptions like compatible maps of type (A) and weakly biased maps in which the maps satisfy di®erent types of rational contractive conditions. These results improve and extend some of the known results of Fisher [9], Jeong and Rhoades [10].
Existence of common fixed points of generalized almost weakly contractive maps
G. V. R. Babu,P. D. Sailaja 장전수학회 2013 Proceedings of the Jangjeon mathematical society Vol.16 No.1
We introduce the concept of `generalized almost weakly contractivemaps', which include both the class of `generalized weakly contractivemaps' and the class of all maps satisfying `generalized condition (B)',and we prove a common ¯xed point theorem for a pair of selfmapssatisfying generalized almost weakly contractive condition. Thistheorem generalizes the result of Abbas, Babu and Alemayehu [2]. Wealso answer an open question posed by Abbas, Babu and Alemayehu[2] in an a±rmative way.
COMMON FIXED POINTS OF TWO PAIRS OF GENERALIZED WEAKLY CONTRACTIVE MAPS
G. V. R. BABU,K. NAGESWARA RAO,G. N. ALEMAYEHU 장전수학회 2010 Advanced Studies in Contemporary Mathematics Vol.20 No.4
We define generalized weakly contractive condition for two pairs of selfmaps and prove the existence of common fixed points of these maps under the assumptions that these two pairs of maps are weakly compatible in a complete metric space. The same is extended to a sequence of selfmaps. Also, we prove the same for four such selfmaps in which one pair is compatible, reciprocal continuous and the other one is weakly compatible.
Weakly biased maps and common fixed point theorems under rational inequality
G. V. R. Babu,M. V. R. Kameswari 장전수학회 2008 Advanced Studies in Contemporary Mathematics Vol.17 No.1
The aim of this paper is to prove a common fixed point theorem for two pairs of selfmaps in a complete metric space (Theorem 3.3 ) in which one pair is compatible maps of type (A) and reciprocally continuous and the other one is a pair of weakly biased maps, using contraction condition involving rational expressions. This result partially generalizes the results of Jeong and Rhoades [1]. Similar results are proved in metric spaces, and compact metric spaces too.
Common fixed point theorems for a pair of compatible maps using a control function
G. V. R. Babu,K. N. V. V. Vara Prasad 장전수학회 2007 Proceedings of the Jangjeon mathematical society Vol.10 No.1
The purpose of this paper is to establish a common fixed point theorem for a pair of selfmaps of a complete metric space by applying the technique altering distances between the points, using a control function, which is our main result. Also it is extended to a sequence of selfmaps. These results generalize the results of Babu and Ismail [1], Is´eki [2], Singh [17] and Som [18].
Common fixed point theorems involving two generalized altering distance functions in four variables
G. V. R. Babu,G. Lalitha,M. L. Sandhya 장전수학회 2007 Proceedings of the Jangjeon mathematical society Vol.10 No.1
The main purpose of this paper is to obtain a common fixed point result (Theorem 2.2) by using two generalized altering distance functions involving four variables for a pair of selfmaps. It is extended to a sequence of selfmaps.
G. V. R. BABU,G. N. ALEMAYEHU 장전수학회 2011 Proceedings of the Jangjeon mathematical society Vol.14 No.1
We prove a common ¯xed point theorem for two pairs of selfmaps in a complete metric space in which one pair is compatible and reciprocally continuous and the other one is a pair of weakly biased maps, satisfying weakly contractive condition involving rational expressions. Also, it is proved that the same is true when `compatibile maps' is replaced by `compatible maps of type (A)'. These results partially generalize the results of Babu and Kameswari [3] and Jeong and Rhoades [5].

<P>We report a new measurement of the exclusive e(+) e(-) -> D-(*()+/-)*D--/+ cross sections as a function of the center-of-mass energy from the D-(*D-)+/-*(-/+) threshold through root s = 6.0 GeV, using the initial-state radiation technique. The analysis is based on a data sample collected with the Belle detector with an integrated luminosity of 951 fb(-1). The accuracy of the cross section measurement is increased by a factor of 2 over the first Belle study. We perform the first angular analysis of the e(+) e(-) -> D*D-+/-*(-/+) process and decompose this exclusive cross section into three components corresponding to the D * helicities.</P>

<P><B>Abstract</B></P> <P>In the present work, we prepared magnesium ferrite/molybdenum trioxide (MFMO) nanocomposite using mechano chemical mixing method for humidity sensor at room temperature. Enhancement in active sites for water adsorption in the composite due to the presence of MoO<SUB>3</SUB> confirmed from X-ray diffraction (XRD) studies. Change in grain size distribution and increase in intergranular pores in the composite favouring water adsorption confirmed from its scanning electron microscopy (SEM) image. Increased agglomeration of nano sized particles and improved crystallinity of the composite confirmed from Transmission electron microscopy (TEM) studies and selected area electron diffraction (SAED) pattern. The composite showed maximum sensing response of 4902 as against 183 of MF in the range 11%–97% RH. The response and recovery times of the composite were found to be 45 s and 74 s respectively while those of MF 225 s and 364 s respectively. The nanocomposite sample showed stable humidity sensing ability and a low humidity hysteresis. Molybdenum trioxide plays a major role in enhancing the humidity sensing performance of MFMO composite at room temperature. The sensing mechanism discussed on the basis of chemisorptions, physisorption and capillary condensation processes.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Humidity sensing response of magnisium ferrite (MF) and magnesium ferrite-molybdenum trioxide (MFMO) composite presented. </LI> <LI> The MFMO showed maximum sensing response of 4902 as against 183 of MF in the range 11%-97% RH. </LI> <LI> The response and recovery times of the composite were found to be 45 s and 74 s respectively. </LI> <LI> The sensing mechanism MFMO discussed on the basis of chemisorptions, physisorption and capillary condensation processes. </LI> </UL> </P>
