Classification of Finite Coloured Linear Orderings
(Order, 2010-09-07)This paper concerns the classification of finite coloured linear orders up to n-equivalence. Ehrenfeucht–Fraïssé games are used to define what this means, and also to help analyze such structures. We give an explicit bound ... -
Countably categorical coloured linear orders
(Math. Log. Quart, 2010-03-18)In this paper, we give a classification of (finite or countable) ℵ0-categorical colored linear orders, generalizing Rosenstein’s characterization of ℵ0-categorical linear orderings. We show that they can all be built from ... -
Counting negative eigenvalues of one-dimensional schrodinger operators with Singular potentials
(Gulf Journal of Mathematics, 2019)In this paper, we extend the well-known estimates for the number of negative eigenvalues of one-dimensional Schrodinger operators with potentials that are absolutely continuous with respect to the Lebesgue measure to the ... -
Ehrenfeucht-fra¨ iss´e games on a class of Scattered linear orders
(arXiv preprint arXiv, 2018-01-02)Two structures A and B are n-equivalent if player II has a winning strategy in the n-move Ehrenfeucht-Fra¨ıss´e game on A and B. In earlier papers we studied n-equivalence classes of ordinals and coloured ordinals. In this ... -
Eigenvalue Bounds for a Class of Schrödinger Operators in a Strip
(Journal of Mathematics, 2018-12-12)This paper is concerned with the estimation of the number of negative eigenvalues (bound states) of Schrodinger operators in a strip subject to Neumann boundary conditions. The estimates involve weighted 𝐿1 norms and 𝐿 ... -
Enhancing teachers’ and students’ conceptual understanding of physics through smart classrooms and comprehensive assessment management information system
(Cogent Education, 2024)This study investigates the effects of smart classrooms, comprehensive assessment management information systems, and remediation teaching techniques on teachers ‘and student’s conceptual understanding of physics. The ... -
Estimates for the number of eigenvalues of two dimensional Schr odinger operators lying below the essential spectrum
(arXiv preprint arXiv, 2016-09)The celebrated Cwikel-Lieb-Rozenblum inequality gives an upper estimate for the number of negative eigenvalues of Schr odinger operators in dimension three and higher. The situation is much more difficult in the two ... -

The fundamental solution of the one–dimensional elliptic operator and its application to solving the advection–diffusion equation
(Research gate, 2020)The advection–diffusion equation is first formulated as a boundary integral equation, suggesting the need for an appropriate fundamental solution to the elliptic operator. Once the fundamental solution is found, then a ... -
