  • On the Rth-order nonhomogeneous recurrence relation and some generalized fibonacci sequences 
    Andrade, A.; Pethe, S.P. (Fibonacci Quarterly. 30(3); 1992; 256-262.)
  • On piecewise constant delay differential-equations 
    Jayasree, K.N.; Deo, S.G. (Journal of Mathematical Analysis and Applications. 169(1); 1992; 55-69.)
    Some results for piecewise constant linear delay differential equations are obtained. They include existence and uniqueness theorems, a variation of parameters formula, integral inequalities, the oscillation property, and ...
  • A generalization of arcangelis method for ill-posed problems leading to optimal rates 
    Nair, M.T. (Integral Equations and Operator Theory. 15(6); 1992; 1042-1046.)
    Schock(1984) considered a general a posteriori parameter choice strategy for the regularization of ill-posed problems which provide nearly the optimal rate of convergence. We improve the result of Schock and give a class ...
  • On uniform-convergence of approximation methods for operator-equations of the 2nd kind 
    Nair, M.T. (Numerical Functional Analysis and Optimization. 13(1-2); 1992; 69-73.)
    Schock (1985) has considered the convergence properties of various Galerkin-like methods for the approximate solution of the operator equation of the second kind x - Tx = y, where T is a bounded linear operator on a Banach ...
  • Variation of parameter formula for the equation of Cooke and Wiener 
    Jayasree, K.N.; Deo, S.G. (Proceedings of the American Mathematical Society. 112(1); 1991; 75-80.)
    A variation of parameters and Gronwall type integral inequality are proved for a differential equation involving piecewise alternately retarded and advanced argument.
  • Optimality of nonlinear control systems 
    Ganesh, M.; Joshi, M.C. (Nonlinear Analysis, Theory, Methods and Applications. 16(6); 1991; 553-566.)
  • Superconvergence of modified projection method for integral equations of the second kind 
    Nair, M.T.; Anderssen, R.S. (Journal of Integral Equations and Applications. 3(2); 1991; 255-269.)
    Recently, Nair proposed a modification for the projection (Galerkin) method for the approximate solution of second kind integral equations and established conditions under which it was superconvergent (relative to the ...
  • Computable error-estimates for Newton's iterations for refining invariant subspaces 
    Nair, M.T. (Indian Journal of Pure and Applied Mathematics. 21(12); 1990; 1049-1054.)
    Chatelin has established, under assumptions on the unknown invariant subspace, the quadratic convergence of Newton's iterative refinements. We modify the procedure in line with Demmel's suggestions and obtain a criterion ...
  • On a Volterra Stieltjes integral equation 
    Vaz, P.T.; Deo, S.G. (Journal of Applied Mathematics and Stochastic Analysis. 3(3); 1990; 177-191.)
    The paper deals with a study of linear Volterra integral equations involving Lebesgue-Stieltjes integrals in two independent variables. The authors prove an existence theorem using the Banach fixed-point principle. An ...
  • Eigenelements of perturbed operators 
    Limaye, B.V.; Nair, M.T. (Journal of the Australian Mathematical Society (Series A). 49(1); 1990; 138-148.)
    Let lambda(0) be a semisimple eigenvalue of an operator T(0). Let gamma(0) be a circle with centre lambda s(0) containing no other spectral value of T(0). Some lower bounds are obtained for the convergence radius of the ...
