On Difference Schemes Approximating First-Order Differential Equations and Defining a Projective Correspondence Between Layers
Autor: M. D. Malykh, E. A. Ayrjan, Leonid A. Sevastianov
Publikováno v: Journal of Mathematical Sciences. 240:634-645
It is well known that there are remarkable differential equations that can be integrated in CAS, but admit several inequivalent approaches to their description. In the present paper, we discuss remarkable differential equations in another sense, name

On the Representation of Electromagnetic Fields in Discontinuously Filled Closed Waveguides by Means of Continuous Potentials
Autor: M. D. Malykh, L. A. Sevast’yanov
Publikováno v: Computational Mathematics and Mathematical Physics. 59:330-342
A closed waveguide of a constant cross section $$S$$ with perfectly conducting walls is considered. It is assumed that its filling is described by function $$\varepsilon $$ and $$\mu $$ invariable along the waveguide axis and piecewise continuous ove

Symbolic-numeric implementation of the four potential method for calculating normal modes of square electromagnetic waveguide with rectangular insert
Autor: M. D. Malykh, A. A. Tiutiunnik
Publikováno v: PROCEEDINGS OF THE INTERNATIONAL CONFERENCE OF COMPUTATIONAL METHODS IN SCIENCES AND ENGINEERING 2019 (ICCMSE-2019).
In this paper, the Maple computer algebra system is used to construct a symbolic-numeric implementation of the method for calculating normal modes of square closed waveguides in a vector formulation. The method earlier proposed by Malykh et al. [M.D.

On Transcendental Functions Arising from Integrating Differential Equations in Finite Terms
Autor: M. D. Malykh
Publikováno v: Journal of Mathematical Sciences. 209:935-952
In this paper, we discuss a version of Galois theory for systems of ordinary differential equations in which there is no fixed list of allowed transcendental operations. We prove a theorem saying that the field of integrals of a system of differentia

On a class of nonlocal parabolic equations
Autor: A. N. Bogolyubov, M. D. Malykh
Publikováno v: Computational Mathematics and Mathematical Physics. 51:987-993
We consider a boundary value problem for parabolic equations with nonlocal nonlinearity of such a form that favorably differs from other equations in that it leads to partial differential equations that have important properties of ordinary different
