Dirac Integral Equations for Dielectric and Plasmonic Scattering [PDF]

open access: yes, 2021
A new integral equation formulation is presented for the Maxwell transmission problem in Lipschitz domains. It builds on the Cauchy integral for the Dirac equation, is free from false eigenwavenumbers for a wider range of permittivities than other known ...

Families of Integrable Equations [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2011
We present a method to obtain families of lattice equations. Specifically we focus on two of such families, which include 3-parameters and their members are connected through Bäcklund transformations. At least one of the members of each family is integrable, hence the whole family inherits some integrability properties.

Comparison of the Orthogonal Polynomial Solutions for Fractional Integral Equations

open access: yesMathematics, 2019
In this paper, a collocation method based on the orthogonal polynomials is presented to solve the fractional integral equations. Six numerical examples are given to illustrate the method. The results are compared with the other methods in the literature,

Regularised discretisations obtained from first‐kind Fredholm operator equations

open access: yesIET Microwaves, Antennas & Propagation, 2021
Judicious discretisations of certain first‐kind Fredholm operator equations are tantamount to Fredholm infinite‐matrix equations of the second kind. We give detailed explanations for the occurrence of this interesting and useful phenomenon and carefully ...

Generalized Bihari Type Integral Inequalities and the Corresponding Integral Equations

open access: yesJournal of Inequalities and Applications, 2009
We study some special nonlinear integral inequalities and the corresponding integral equations in measure spaces. They are significant generalizations of Bihari type integral inequalities and Volterra and Fredholm type integral equations.
