Öğe The double x sequences(Selcuk University Research Center of Applied Mathematics, 2010) Subramanian, N.Let denote the space of all double entire sequence. Let 2 denote the space of all double analytic sequences, let x2 denote the space of all double x sequences. This paper is devoted to a study of the general properties of x2.Öğe FT-IR, FT-Raman spectra, density functional computations of the vibrational spectra and molecular conformational analysis of 2,5-di-tert-butyl-hydroquinone(PERGAMON-ELSEVIER SCIENCE LTD, 2011) Subramanian, N.; Sundaraganesan, N.; Dereli, O.; Turkkan, E.The purpose of finding conformer among six different possible conformers of 25-di-tert-butyl-hydroquinone (DTBHQ), its equilibrium geometry and harmonic wavenumbers were calculated by the B3LYP/6-31G(d,p) method. The infrared and Raman spectra of DTBHQ were recorded in the region 400-4000 cm(-1) and 50-3500 cm(-1), respectively. In addition, the IR spectra in CCl(4) at various concentrations of DTBHQ are also recorded. The computed vibrational wavenumbers were compared with the IR and Raman experimental data. Computational calculations at B3LYP level with two different basis sets 6-31G(d,p) and 6-311++G(d,p) are also employed in the study of the possible conformer of DTBHQ. The complete assignments were performed on the basis of the potential energy distribution (PED) of the vibrational modes, calculated using VEDA 4 program. The general agreement between the observed and calculated frequencies was established. (C) 2011 Elsevier B.V. All rights reserved.Öğe A new double x sequence space defined by a modulus function(Selcuk University Research Center of Applied Mathematics, 2011) Subramanian, N.; Krishnamoorthy, S.; Balasubramanian, S.The idea of single difference sequence space was introduced by Kizmaz[31] and this concept was generalized by various authors. In this paper generalized we define the double difference space ?(?^{m},f,p,q,s) on a semi normed complex linear space by using modulus function and we give various properties and some inclusion relations on this space. Further more we study some of its properties solidity, etc.Öğe A subset of the space of the ?2 sequences(Selcuk University Research Center of Applied Mathematics, 2011) Subramanian, N.Let ?2 denote the space of all Pringsheim sense double gai sequences. Let ?2 denote the space of all Pringsheim sense double analytic sequences. This paper is devoted to a study of the general properties of Sectional space ?2s of ?2.
