On the approximate solution of the Cauchy problem for the Helmholtz equation on the plane [PDF]

open access: yesComputational Algorithms and Numerical Dimensions
In this paper, approximate solutions of the Cauchy problem for the Helmholtz equation on a two-dimensional bounded region are found. The problem under consideration belongs to the problems of mathematical physics, in which there is no continuous ...

An analog of the Cauchy formula for certain Beltrami equations

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2019
The Beltrami differential equations are intrinsic generalizations of the Cauchy–Riemann system in complex analysis. Their solutions generalize holomorphic functions. As known, solutions to many problems of the complex analysis are based on application of

On Problem of Internal Boundary Control for String Vibration Equation

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2021
The article deals with the vibration control problem described by one dimensional wave equation with integral type boundary condition. As usual, the initial and final moments of time for arbitrary displacements and velocities of the wave are specified ...

Boundary value problems on fractal hypersurfaces for the quaternionic hermitian system in R-4n [PDF]

open access: yes, 2014
In this paper we formulate and study Dirichlet and jump problems on fractal hypersurfaces in R4n for quaternionic Hermitian monogenic functions, using a circulant matrix approach.

Differential forms and Clifford analysis [PDF]

open access: yes, 2016
In this paper we use a calculus of differential forms which is defined using an axiomatic approach. We then define integration of differential forms over chains in a new way and we present a short proof of Stokes' formula using distributional techniques.

A Cauchy kernel for slice regular functions

open access: yes, 2009
In this paper we show how to construct a regular, non commutative Cauchy kernel for slice regular quaternionic functions. We prove an (algebraic) representation formula for such functions, which leads to a new Cauchy formula.

Higher order Borel–Pompeiu representations in Clifford analysis [PDF]

open access: yes, 2016
In this paper, we show that a higher order Borel–Pompeiu (Cauchy–Pompeiu) formula, associated with an arbitrary orthogonal basis (called structural set) of a Euclidean space, can be extended to the framework of generalized Clifford analysis. Furthermore,

CARLEMAN'S FORMULA OF A SOLUTIONS OF THE POISSON EQUATION IN BOUNDED DOMAIN

open access: yesUral Mathematical Journal, 2021
We suggest an explicit continuation formula for a solution to the Cauchy problem for the Poisson equation in a domain from its values and values of its normal derivative on a part of the boundary.

Construction of the solution of the boundary value problem for integro differential equation with a small parameter in highest derivatives

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2016
The article is devoted to the study analytical formula of solution of boundary value problem with initial jump for a linear integro-diferential equation of n + m order with a small parameter in the highest derivatives.
