Cubic nonlinear differential system, their periodic solutions and bifurcation analysis
AIMS Mathematics, 2021 In this article, periodic solutions from a fine focus $ U = 0 $, are accomplished for several classes. Some classes have polynomial coefficients, while the remaining classes $ C_{14, 7} $, $ C_{16, 8} $ and $ C_{5, 5}, $ $ C_{6, 6} $ have non-homogeneous

New exact solutions for the two-dimensional Broadwell system [PDF]
Известия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2022 In this paper, we consider the discrete kinetic Broadwell system. This system is a nonlinear hyperbolic system of partial differential equations. The two-dimensional Broadwell system is the kinetic Boltzmann equation, and for this model momentum and ...

SICE Journal of Control, Measurement, and System Integration, 2020 This paper proposes a recursive elimination method for optimal filtering problems of a class of discrete-time nonlinear systems with non-Gaussian noise. By this method, most of the computations to solve an optimal filtering problem can be carried out off-

New Specific and General Linearization Formulas of Some Classes of Jacobi Polynomials
Mathematics, 2020 The main purpose of the current article is to develop new specific and general linearization formulas of some classes of Jacobi polynomials. The basic idea behind the derivation of these formulas is based on reducing the linearization coefficients which ...

Mixed algorithm for solving boundary value problem
Computer Assisted Methods in Engineering and Science, 2023 Symbolic computation has been applied to Runge-Kutta technique in order to solve two-point boundary value problem. The unknown initial values are considered as symbolic variables, therefore they will appear in a system of algebraic equations, after the ...
