    Nair, M.T. (Proceedings of the American Mathematical Society. 123(6); 1995; 1845-1850.)
    Farid (1991) has given an estimate for the norm of a perturbation V required to obtain an eigenvector for the perturbed operator T + V within a given ball centered at a given eigenvector of the unperturbed (closed linear) ...
  • On strongly stable approximations 
    Nair, M.T. (Journal of the Australian Mathematical Society Series A-Pure Mathematics and Statistics. 52; 1992; 251-260.)
    Ahues (1987) and Bouldin (1990) have given sufficient conditions for the strong stability of a sequence (T(n)) of operators at an isolated eigenvalue of an operator T. This paper provides a unified treatment of their results ...
  • On symmetry analysis in finding solutions of the one dimensional wave equation 
    Lobo, J.Z.; Valaulikar, Y.S. (Proc. of Int. Conf. on Applied Mathematics & Computational Sciences (ICAMCS-2019), Ed. by: Jogendra Kumar, Seema Yadav, Fateh Singh. 2020; 133-141.)
    In this paper we obtain the Lie invariance condition for second order partial differential equations. This condition is used to obtain the determining equations of the 1-dimensional wave equation with constant speed. The ...

  • On the crystal growth of 'tris thiourea chromium(III) sulphate', 'potassium thiourea thiocyanide' and 'bis thiourea iron(II) sulphate' 
    Srinivasan, B.R.; Tylczynski, Z. (Journal of Thermal Analysis and Calorimetry. 121(3); 2015; 1183-1184.)
    We argue that the 'tris thiourea chromium(III) sulphate' crystal (Madhurambal et al. in J Therm Anal Calorim 108:905-910, 2012), potassium thiourea thiocyanide crystal (Ramamurthi et al. in J Therm Anal Calorim 104:943-947, ...
  • On the distorted {NiN6} octahedron in hexakis(imidazole)nickel(II) bis(4-nitrobenzoate) dihydrate 
    Srinivasan, B.R.; Sawant, J.V.; Raghavaiah, P. (Indian Journal of Chemistry Section A-Inorganic Bio-Inorganic Physical Theoretical and Analytical Chemistry. 48(2); 2009; 181-188.)
    The reaction of [Ni(H2O)(6)]Cl-2 with the sodium salt of 4-nitrobenzoic acid (4-nbaH) in the presence of imidazole results in the formation of the title compound hexakis(imidazole)nickel(II) bis(4-nitrobenzoate) dihydrate ...

    Petrosyan, A.M.; Srinivasan, B.R. (Optik: International Journal for Light and Electron Optics. 127(8); 2016; 3989-3990.)
    We prove that a so-called "Semi Organic Non Linear Optical Crystal: Diglycine ammonium sulphate" reported by B. Helina, (Optik 127 (2016) 1401-1404) is not a new semi organic nonlinear optical crystal. Instead it is the ...

    Petrosyan, A.M.; Srinivasan, B.R. (Journal of Thermal Analysis and Calorimetry. 120(2); 2015; 1077-1078.)
    We argue that the "L-arginine acetamide" crystal reported by Anitha et al. (J Therm Anal Calorim 119:785–789, 2015) is actually the well-known monoclinic form of anhydrous L-arginine hydrochloride crystal.
