COMPOSITE LAGUERRE PSEUDOSPECTRAL METHOD FOR FOKKER-PLANCK EQUATIONS
Mathematical Modelling and Analysis, 2023 A composite generalized Laguerre pseudospectral method for the nonlinear Fokker-Planck equations on the whole line is developed. Some composite generalized Laguerre interpolation approximation results are established. As an application, a composite Laguerre pseudospectral scheme is provided for the problems of the relaxation of fermion and boson gases.

A family of root-finding methods with accelerated convergence [PDF]
, 2006 A parametric family of iterative methods for the simultaneous determination of simple complex zeros of a polynomial is considered. The convergence of the basic method of the fourth order is accelerated using Newton's and Halley's corrections thus ...

On the Laguerre Method for Separating the Roots of Algebraic Equations [PDF]
Proceedings of the American Mathematical Society, 1957 where f--f(x), f(x) = 0 is an algebraic equation of degree N with real roots and x an arbitrary real number, separate the roots of the equation. This proposition was also discussed by Ch. Hermite [2 ] and by E. Bodewig [N]. According to the proposition there will be at least one root of the equation between u and v. A generalization of the relation (1),

The Hall Effects of Vortex Light in Optical Materials
Advanced Photonics Research, EarlyView.This article models optical materials as curved spacetime to investigate light propagation, finding that the deflection angle for light with spin σ and intrinsic orbital angular momentum ℓ follows ϑ ∝ 2σ + ℓ$\vartheta \propto 2 \text{&sgr; } + ℓ$.
