A "converse'' stability condition is necessary for a compact higher order scheme on non-uniform meshes for the time-dependent Schrödinger equation
(Applied mathematics letters, 2018)The stability bounds and error estimates for a compact higher order Numerov-Crank-Nicolson scheme on non-uniform spatial meshes for the 1D time-dependent Schrödinger equation have been recently derived. This analysis has ... -
A compact higher-order finite-difference scheme for the wave equation can be strongly non-dissipative on non-uniform meshes
(Applied mathematics letters, 2021)We study necessary conditions for stability of a Numerov-type compact higher-order finite-difference scheme for the 1D homogeneous wave equation in the case of non-uniform spatial meshes. We first show that the uniform in ... -

A complete metric in the function space Dα[0,∞)
(Acta applicandae mathematicae : an international survey journal on applying mathematics and mathematical applications, 2003)Subspaces Dα of D[0,1] and of D[0,∞) are defined. With constructed metrics dα, Dα are shown to be complete separable metric spaces. Conditions for tightness of probability measures in Dα are given. -
A complex proportional assessment method for group decision making in an interval-valued intuitionistic fuzzy environment
(Technological and economic development of economy, 2013)Multi-criteria decision making is an implicational field that concerns with selecting or designing the best scenarios among a finite set of scenarios based on a finite set of criteria. Different methods and techniques for ... -
A family of univalent polynomials in an angular domain
(Siberian mathematical journal, 2009)We study the properties of symmetric polynomials of a particular form and use them to find a maximal angular domain of univalence for some family of polynomials. -
A finite-difference scheme for a nonlinear model of wood drying process
