    The Role of Physical, Human and Social Capital in Regional Financial Development Differences: An Analysis of Turkish Provinces Ercan Dulgeroglu , Sibel Bali Eryigit , Kadir Y. Eryigit and Filiz Gaygusuz Abstract With the undeniable importance of the financial markets in the economy, the factors stimulating financial development have started to be researched, particularly in recent times in a more intensive way. Starting from this point, the driving force of this study is both to contribute to international literature in this field and to fill a gap in the literature related to Turkey. The main purpose of this study is to explain the causes of regional financial development differences on the basis of capital accumulation. In order to answer the question ‘What is the effect and degree of importance of physical, human and social capital on the differences in regional financial development?’, in this study some indexes for financial development and each type of capital accumulation will be calculated using kernel principle components analysis and depending on the annual data of 81 provinces covering the period 2005 – 2009. As an index, the capital measurements can be seen in a comprehensive form allowing for more accurate measurement and evaluation of both the capital accumulation and financial development. By using the calculated indexes, then, financial development differences are evaluated with spatial panel data methods developed by Elhorst (2003). In this context, to our knowledge, this study is the first to take into account the effects of each type of capital on financial development in a model simultaneously. Keywords: Financial development, physical capital, human capital, social capital, spatial panel data analysis,

    Scaling of the critical temperature and quark potential with a renormalization group improved SU(3) gauge action

    Get PDF
    We study the scaling property of the ratio of the critical temperature TcT_c to the square root of the string tension σ\sigma in the SU(3) pure gauge theory using a renormalization group improved action. We first determine the critical coupling ÎČc\beta_c on lattices with temporal extension Nt=4N_t=4 and 6, and then calculate the static quark potential at the critical couplings on lattices at zero temperature. The values of Tc/σT_{c}/\sqrt{\sigma} in the infinite volume limit are identical within errors, while they are slightly larger than the value extrapolated to the continuum limit with the standard action. We also note that the rotational invariance of the static quark potential is remarkably restored in the both cases, and that the potential V(R)V(R) in physical units scales in the whole region of RR investigated.Comment: 3 pages of Latex, 5 PostScript figures, Talk presented at LATTICE96(finite temperature

    Comparing the QCD potential in Perturbative QCD and Lattice QCD at large distances

    Get PDF
    We compare the perturbatively calculated QCD potential to that obtained from lattice calculations in the theory without light quark flavours. We examine E_tot(r) = 2 m_pole + V_QCD(r) by re-expressing it in the MSbar mass m = m^MSbar(m^MSbar) and by choosing specific prescriptions for fixing the scale mu (dependent on r and m). By adjusting m so as to maximise the range of convergence, we show that perturbative and lattice calculations agree up to 3*r_0 ~ 7.5 GeV^-1 (r_0 is the Sommer scale) within the uncertainty of order Lambda^3 r^2.Comment: Version to appear in Eur.J.Phys; 16 pages, 7 figure

    A fresh look on the flux tube in Abelian-projected SU(2) gluodynamics

    Get PDF
    We reconsider the properties of the QQˉQ\bar{Q} flux tube within Abelian-projected SU(2) lattice gauge theory in terms of electric field and monopole current. In the maximal Abelian gauge we assess the influence of the Gribov copies on the apparent flux-tube profile. For the optimal gauge fixing we study the independence of the profile on the lattice spacing for ÎČ=\beta= 2.3, 2.4, and 2.5115 on a 32432^4 lattice. We decompose the Abelian Wilson loop into monopole and photon parts and compare the electric and monopole profile emerging from different sources with the field strength and monopole current within the dual Ginzburg-Landau theory.Comment: 3 pages, 6 figures, Lattice2002(topology

    Thermodynamics and heavy quark potential in N_f=2 dynamical QCD

    Get PDF
    We study N_f=2 lattice QCD with nonperturbatively improved Wilson fermions at finite temperature on 16^3 \cdot 8 lattices. We determine the transition temperature at m_{\pi}/m_{\rho} \sim 0.8 and lattice spacing as small as 0.12fm. The string breaking at T < T_c is also studied. We find that the static potential can be fitted by a simple expression involving string model potential at finite temperature.Comment: 6 pages, 6 figures, contribution to Lattice 2002(topology

    Quark Confinement Physics in Quantum Chromodynamics

    Get PDF
    We study abelian dominance and monopole condensation for the quark confinement physics using the lattice QCD simulations in the MA gauge. These phenomena are closely related to the dual superconductor picture of the QCD vacuum, and enable us to construct the dual Ginzburg-Landau (DGL) theory as an useful effective theory of nonperturbative QCD. We then apply the DGL theory to the studies of the low-lying hadron structure and the scalar glueball properties.Comment: Talk given at 15th International Conference on Particle and Nuclei (PANIC 99), Uppsala, Sweden, 10-16 Jun 1999, 4 page

    Observing Long Colour Flux Tubes in SU(2) Lattice Gauge Theory

    Get PDF
    We present results of a high statistics study of the chromo field distribution between static quarks in SU(2) gauge theory on lattices of volumes 16^4, 32^4, and 48^3*64, with physical extent ranging from 1.3 fm up to 2.7 fm at beta=2.5, beta=2.635, and beta=2.74. We establish string formation over physical distances as large as 2 fm. The results are tested against Michael's sum rules. A detailed investigation of the transverse action and energy flux tube profiles is provided. As a by-product, we obtain the static lattice potential in unpreceded accuracy.Comment: 66 pages, 29 figures, uuencoded latex file with epsfigures (450 K), supplementary full colour figures are available via ftp, CERN-TH.7413/94 (extended version

    Structure of the baryonic flux tube in N_{f}=2 lattice QCD at finite temperature

    Full text link
    We study the flux tube profile in the baryonic system in full QCD at finite temperature on Nt=8N_{t}=8 lattice. We fix the maximally Abelian gauge and measure the monopole and the photon parts of the Abelian action density, the color electric field and the monopole current on both sides of the finite temperature transition. We demonstrate the disappearance of the flux tube in the high temperature phase.Comment: 3 pages, 4 figures, Lattice2003 topolog
