On the solvability of a semi-periodic boundary value problem for the nonlinear Goursat equation

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2021
In this paper, by means of a change of variables, a nonlinear semi-periodic boundary value problem for the Goursat equation is reduced to a linear gravity problem for hyperbolic equations. Reintroducing a new function, the obtained problem is reduced to

A Fuzzy Random Boundary Value Problem

open access: yesAxioms, 2022
A system of generalized fuzzy random differential equations with boundary conditions is investigated, which is a fuzzy version of a system of general random differential equations. We first present random fixed point (RFP) theorems in fuzzy metric space (

TWO-DIMENSIONAL HYBRIDS WITH MIXED BOUNDARY VALUE PROBLEMS

open access: yesActa Polytechnica, 2016
Boundary value problems are considered on a simplex F in the real Euclidean space R2. The recent discovery of new families of special functions, orthogonal on F, makes it possible to consider not only the Dirichlet or Neumann boundary value problems on F,

The Buckling Operator: Inverse Boundary Value Problem

open access: yesMathematics, 2023
In this paper, we consider a zeroth-order perturbation q(x) of the buckling operator Δ2−κΔ, which can be uniquely determined by measuring the Dirichlet-to-Neumann data on the boundary.
