Discontinuous Sturm‐Liouville Problems and Associated Sampling Theories [PDF]
This paper investigates the sampling analysis associated with discontinuous Sturm‐Liouville problems with eigenvalue parameters in two boundary conditions and with transmission conditions at the point of discontinuity. We closely follow the analysis derived by Fulton (1977) to establish the needed relations for the derivations of the sampling theorems ...

Numerical Simulations of Coupled Solitary Waves With Spatially Modulated Non‐Linearity
This study investigates the dynamics of two coupled solitary waves propagating in media characterised by spatially modulated non‐linearity and variable dispersion. By employing numerical simulations of a system of coupled non‐linear Schrödinger equations (NLSEs) with varying coefficients, we analyse how inhomogeneous physical properties influence ...

Purpose This study aims to develop a mathematically cautious and reproducible (q, τ)‐deformed Gegenbauer‐type (DGT) polynomial ((q, τ)‐DGT) for spectral approximation and illustrative diffusion modeling. The revision is motivated by the need to avoid circular definitions, unsupported orthogonality claims, and unstable diffusion sign conventions ...

Using critical point theory due to Bonanno [3], we prove the existence of at least one non-trivial solution for a class of two-point boundary-value problems for fourth-order Sturm-Liouville type equations.

Localised gravity and resolved braneworlds
Deriving an effective massless field theory for fluctuations about a braneworld spacetime requires analysis of the transverse-space-wavefunction’s second-order differential equation. There can be two strikingly different types of effective theory.

F. H. Jackson has introduced a system of numbers called ''basic numbers'' and the corresponding operations of ''basic differentiation'' and ''basic integration'' [see \textit{T. W. Chaundy}, J. Lond. Math. Soc., II. Ser. 37, 126-128 (1962; Zbl 0099.246), for references to the original work of F. H. Jackson].

In Chap. 3 we have seen how the separability of PDEs leads to ordinary differential equations problems, usually of second order. The problem is complemented with B.C.s and the reduction of the initial PDE to second order ODEs often yield a so-called

In the present paper, a discontinuous boundary-value problem with retarded argument at the two points of discontinuities is investigated. We obtained asymptotic formulas for the eigenvalues and eigenfunctions.
