  • On iterative refinements for spectral sets and spectral-subspaces 
    Nair, M.T. (Numerical Functional Analysis and Optimization. 10(9-10); 1989; 1019-1037.)
    Stewart (1971) and Demmel (1987) have proposed iterative procedures for refining invariant subspaces of Hilbert space operators and matrices respectively. In this paper, modifications are proposed for these procedures which ...
  • XANES study of tungsten LIII discontinuity in some rare earth tungstates 
    Vishnoi, A.D.; Sapre, V.B.; Mande, C. (X-Ray Spectrometry. 17(6); 1988; 213-215.)
    The shape and near edge structure of the L sub(III) absorption discontinuity of tungsten in some rare earth tungstates, RE sub(2)(WO sub4))sub(3), were studied using a 40 cm Cauchois-type transmission x-ray spectrograph. ...
  • Self-consistent calculations in the theory of mix-valence 
    Prabhu, R.B.; Tangsali, R.B. (Physica Status Solidi B-Basic Research. 149(2); 1988; 623-632.)
    Self-consistent perturbation theory is employed for the calculation of physical quantities in mixed valence systems. A single impurity U -> infinity Anderson model is considered with and without crystalline field splitting. ...
  • Study of the environment of copper in some ternary chalcogenide by EXAFS spectroscopy 
    Deshpande, A.P.; Sapre, V.B.; Mande, C. (Physica Status Solidi B-Basic Research. 145(1); 1988; 77-88.)
    The EXAFS data of the K absorption discontinuity of copper in some ternary chalcogenides obtained earlier are reanalysed using the graphical method originally proposed by Lytle, Sayers, and Stern. It is shown that the ...
  • A Neutron diffraction investigation of the structure of vitreous 
    Desa, J.A.E.; Wright, A.C.; Sinclair, R.N. (Journal of Non-Crystalline Solids. 99(2to3); 1988; 276-288.)
    Neutron diffraction techniques have been employed to obtain an accurate high-resolution real space correlation function for vitreous GeO2. The GeO bond length is found to be 1.739 + and the rms bond length variation 0.048 ...
  • Localization of a simple eigenvalue and a corresponding eigenvector 
    Limaye, B.V.; Nair, M.T. (Houston Journal of Mathematics. 14; 1988; 129-141.)
  • Non-linear Integral Inequality in two independent variables 
    Deo, S.G.; Vaz, P.T. (International Journal of Mathematics and Mathematical Sciences, U.S.A. 11(1); 1988; 115-120.)
    In this note, the authors obtain a generalization of the integral inequality of Bihari a nonlinear inequality in two independent variables. With the aid of this inequality a bound for the solution of a nonlinear partial ...
  • Magnetic to non-magnetic crossover phenomena in CeSi(2-x)Ga(x) 
    Priolkar, K.R.; Rao, M.N.; Paranjpe, S.K.; Raj, P.; Sathyamoorthy, A.; Sarode, P.R.; Prabhu, R.B. (Solid State Phys DAE Symp. 39c; 1996; 138.)
  • Group theoretic approach to disordered systems 
    Prahalad, Y.S. (Physics Letters A. 122(6to7); 1987; 335-337.)
    The problem of a quantum particle in a gaussian homogeneous, random potential is shown to admit a stochastic symmetry group and its unitary representations are found. It is pointed out that the theory of group representation ...
  • A modified projection method for equations of the second kind 
    Nair, M.T. (Bulletin of the Australian Mathematical Society. 36(3); 1987; 485-492.)
    A modified projection method is suggested for the approximate solution of second kind equations and it is compared with other methods.
